After Jack escapes the apartment in the car, Alma pulls up and yells at Dylan to never tell her to stay in the car. Dylan then replies "Fine! Now go!" In the reverse angle where Dylan says "Fine!" his jaw doesn't move. Theatrical version only.
At 1:19:00 when Cowan is briefing Evans, Fuller, Rhodes and Dray about the paperwork Rhodes pulled out of the car before it blew up, Cowan mentions the "trigger word". In the very next scene where they are trying to find the safe, Cowan mentions the "trigger word" again, but this time Evans is activated and begins "playing the violin".
When Thaddeus Bradley is explaining to Dylan Rhodes and Alma Dray how he began his career exposing magicians, the camera cuts to Rhodes twice. However, both cuts are exactly the same. All three characters are seated at a table. At different points during the scene, two ladies are seen passing each other on a set of stairs just behind Rhodes' as he tilts his head to listen more intently to Bradley's story. The same cut is used twice.
Near the beginning of the movie Thaddeus says that Lionel Shrike died in his steel safe in the East River. However the newspaper article towards the end of the movie says that Shrike died in the Hudson River.
When Thaddeus comes to wish everyone good luck, Merritt stands to do a quick reading on Thaddeus. You can see Jack in the background changing his position. Switching the camera to Thaddeus and back to Merritt, you see Jack change his position again.
When "Danny" and Henley meet outside the building which they were invited to, Danny takes Henley's invitation card out of her hand and throws it on the ground. But when they are inside she has it. She was not seen picking it up.
When Daniel starts doing a card trick on Thaddeus in their room, all four Horsemen are standing even with each other. A couple shots later, Henley and Jack are both suddenly standing behind Daniel and Merritt. Then a few shots after that, they are even with each other again. Extended version.
When Dylan, Fuller and Cowan watch the Horsemen's YouTube video, the time on the bar at the bottom of the video reads the clip had been going for 2 minutes and 50 seconds just as Merritt finishes saying "We cannot quit now." The shot cuts to Dylan, Fuller and Cowan and doesn't cut back to the video for a good 5 seconds. But when the shot cuts back, it can be seen only 1 second has passed.
In the climax, when the 4 horsemen meet the Eye, the order in which they come is (from the left), Death, Hermit, Priestess, Lover. This is the same, as they enter the 'house' as the Eye says "The real magic is taking 4 strong..." But as he continues the line with "solo acts" the camera angle changes, showing Death at the other end, next to Lover, with no time for Death to do so. Also, after Eye says "Welcome to the Eye", Death jumps the gate into the play area, followed by Hermit, as Priestess and Lover goes through the gate. In the next frame, as they all watch Eye, Hermit and Lover are misplaced. This is okay until the Priestess holds her left hand with the right hand of Lover. However, right in the next shot, as Death climbs the 'wheel', Lover is to the right of Priestess, leaving Hermit to Priestess' left hand side, the position same when they entered into the play area.
When Daniel is in his room and pushes off the woman on top of him, he crawls over to the tarot card in his shoe. When the woman yells "Are you kidding me?", the left shoelace is lying over the left side of the shoe, but when Daniel approaches the shoe in the next shot, the shoelace isn't in the same place.
Daniel finds his card. In a close-up of the card, he has his 4th finger placed on the side of the card, his thumb placed on the bottom of the card and the other three fingers hanging freely. Yet in a reverse angle of the card where the camera is in front of Daniel, he has all five fingers placed on the left side of the card.
When the Horsemen are filming the 5 Pointz video, Daniel begins to say why they are there and is interrupted by Merritt who then says the exact same thing. When Merritt starts speaking, Daniel can be seen smirking. But from a sudden shot of the POV of the camera, Daniel isn't smirking. Extended version.
When Dylan and Alma go to interrogate Daniel, the first shot of Daniel shows him playing with some cards. On the desk is the card box the cards go in. In the next shot, the card box is suddenly in his hand and the cards are suddenly back in the box. Theatrical version only.
At the start of the New Orleans show, Henley is wearing trousers. But by the time, the rabbit trick begins, she is suddenly wearing a dress. She goes back to wearing trousers once she jumps into the bubble.
As Dylan and Fuller approach the Horsemen's apartment, there is a close-up of the apartment door's doorknob that shows the door is only open a few inches. From a low angle of Dylan opening the door, the door is now open almost halfway.
After the Horsemen have left the FBI, Fuller says to Dylan "Guess who was sitting there in the back..." During this shot, two men and a woman are visible in the background are about to walk down a flight of stairs. 2 shots later, there is no sign of them. Then they are visible walking on the sidewalk when the camera is on Dylan in the next shot. In this shot, they walk past Dylan. But 2 shots later, they are still yet to walk past Dylan.
In the very first shot of Dylan, he is shown walking out of a casino with an Indian guy. As his phone rings, he says to the man "Hold up here" and he stands still. In the next shot, 360-degree panning shot around Dylan is shown and the Indian guy has suddenly vanished.
Dylan and Alma go on a plane to New Orleans. In the first shot of the cabin, the shot pans from the passengers over to Dylan and Alma. When the shot stops panning, there are papers on Dylan's table. The paper on top is facing a 12 o'clock direction. Alma asks Dylan to pick out a card and he does. When he puts the card back, the paper on top is now facing a 10 o'clock direction without him ever moving it.
When Dylan is shown the interrogation tape of Daniel stealing his phone, the video frame shows no lower than Daniel's belt as he tells them to zoom in tighter. But in a close-up of the video when Dylan says "Tighter" a second time, the video frame now shows almost half of his trousers visible within the video frame.
On the bridge as Jack Wilder's car wrecks and blows up in flames it is resting against the center divider of the four lanes. In the next shot, from an above angle, most likely a helicopter, the car is visibly burning on the outside lane of the bridge away from the center divider.
When Henley is in the tank, supposedly getting eaten by piranhas, there is a guy in a shirt with a blue hat standing in front of it. In one shot, the guy takes his hands off the tank, but by the next shot, his hands are back on it.
When Arthur Tressler contacts Thaddeus to ask him how well is his money being spent, Thaddeus is shown inside his car with his camera crew and replies with "Exceedingly well." During this shot, Thaddeus is shown lowering his car window until it has reached the bottom. In the next shot, as Thaddeus says "See for yourself", the shot shows the window only half rolled down.
When Jack is being chased by Dylan and Alma, he drives onto a sidewalk and knocks into two bikes. He continues driving and most of the two bikes slide off the car, leaving one of the bike wheels stuck to the bumper. In the next shot, almost the entire bike is still stuck to the bumper.
As Jack shows Dylan the cards (before throwing them at him), Dylan then says "Really?" And we can see there is already a huge red scratch on his cheek, which isn't caused until the cards are thrown. It couldn't have been from when Jack threw the flash paper at Dylan because no scratch mark was visible when that happened.
When Dylan and Alma are on the plane, as the shot pans around to them, Alma has a drink with a stirrer, which is on the edge of the cup. Alma then asks Dylan to pick out a card and put it back in the deck. If you look at Alma's drink, the stirrer is now sticking upwards in the middle of the cup.
When Merritt says to the cheating husband "And if you even see or even think of Janet, you're gonna picture me, naked", there are a few strands of hair along his fringe. Merritt then wakes up the husband's wife and the few strands of hair along his fringe have decreased.
When Alma lets go of Dylan's head after pushing him on the table, she is noticeably facing Dylan as the shot ends. In the next shot, she is suddenly facing 180 degrees in the opposite direction with no time to do so.
As Daniel is performs his card trick on the fan, there is a guy visible behind the woman who is behind the fan. He remains in his same position throughout the scene. Yet from a wide angle of the audience cheering at Daniel, the fan is visible, but the guy two places behind her has been replaced by a completely different person.
For Henley's trick she has handcuffs chained to her and is dropped into a tank. In one of the reverse angles, she has both of her arms stretched out. But in a close-up of her arms, she now has her arms extended with them in front of her. She is saying the same line during all of the shots as this happens so it couldn't have had anything to do with several seconds passing between shots.
When Jack performs his magic trick on the spoon, a man figures out how he did it and demands $100. In a close-up of his wallet, the wallet is opened. But in the wide angle, the wallet is suddenly closed.
When Jack picks up the wet cloth to shove into Agent Fuller's mouth, there is a tap in a sink with a cloth and the tap is pointed to the left. Then as Jack drags Fuller over to the garbage disposal in the sink, the tap is suddenly pointed forwards. And when Jack shoves Fuller's jacket sleeves into the garbage disposal, the tap is pointing to the right.
When Jack gives the man the $100 for figuring out his trick, he leaves, walks down a flight of steps and turns around a corner and walks by a mysterious man. In the next shot, he is shown walking past the exact same corner at the edge of the steps a second time.
At Pont des Arts in Paris when Dylan reveals his true self to Alma, the right page shown in the newspaper changes layout and stories. An earlier shot does not show a story about 12-year-old Dylan while it's there in the second shot.
There's a space issue with the scenes of the safe in the truck. They show Agent Fuller coming around on the (viewer's) left side of the safe to show the Horsemen video. However, when we first see the safe in the truck, there is absolutely no way a man of Fuller's size can fit in the gap between the safe and truck wall.
When the car crashes on the bridge, it slides against the barrier on the middle of the road and flips over. As it slides, the bus on the next lane is seen to be more ahead of the car. The shot then cuts to Fuller yelling out "Oh, shit!" and it cuts back to he car flipping over. Only now, the bus is suddenly right next to the car, ready to drive past it.
On the bridge, as Dylan and Alma chase Jack, a bus drives in the way of Jack's car. When Jack's car is shown again, a quick shot from the front of the bus is shown. Although the light reflects on the window and we can't see the driver, we can see, just for a moment, that there are hardly any passengers on the bus. Later on, when Thaddeus is explaining how the Horsemen faked Jack's death, Merritt is shown to have been the driver of the bus, and in the passenger seats are dummies, rather than the almost empty bus shown before.
When the car blows up, visible to the right of the car is a tyre that fell off during the crash. The explosion is then seen going over the tyre. When the fire clears the tyre isn't there anymore, but it reappears a few shots later.
As Dylan chases the Horsemen through New Orleans, he runs onto a street where there is a huge crowd. A police car stops in front of Dylan. In the shot where the police car stops, Dylan is standing next to the car, but standing in front of the car in the next shot.
When Thaddeus is filming Magic Unmasked, directly behind him is a stand of magic items. When the crew leaves to let Thaddeus and Tressler talk, behind Thaddeus is now a completely different collection.
(Extended Version) After Dylan Rhodes has been tackled by the 12 hypnotized audience members and the Four Horsemen are ascending above the stage, a guy in a grey suit and Alma Dray can be seen standing next to the audience members on the stage, with the guy pulling one of them off Rhodes. A wide shot is then shown and no one is standing beside the pile (Dray is visible, but is almost off the stage).
At the apartment, Dylan takes the Guardians of Horus off Alma and goes to the living room and places it on a table. The scene cuts to Alma sleeping and the scene cuts back to Dylan. In the first shot, his gun is placed next to the book and is facing a 7 o'clock angle and is a few inches away from the edge of the table. In the following shot, the gun is now facing a 12 o'clock direction and on the edge of the desk. Extended version.
As the FBI agents re-watch the interrogation tape, there is a time code on the right hand top corner. When Dylan says "That's where he took my phone", the time code on the top right corner reads 13 minutes and 33 seconds. The shot then cuts to Dylan for only a second or two, but in the next shot, the video is still visible in the background, paused at 13 minutes and 39 seconds.
When Alma walks over to the bench on the bridge, there is a woman sitting on it and a guy standing next to the bench. When she sits down, the woman sitting and the guy standing next to it have instantly vanished.
When Henley gets the "locks stuck" in the tank, she shouts for help. The timer goes past 49 seconds. A member of the audience runs over to the pipe 15 meters away from the tank, runs back to the tank and hits the pipe twice - the timer then shows 55 seconds. Running to get the pipe and return took longer than 6 seconds.
When the audience's account balances start rising, Dylan asks Fuller if it is for real. The scene cuts to Fuller in the van. To the side of him is a woman on a computer. Next to her is another computer that shows green encryption. In a close-up, the encryption is orange, then back to green.
During their conversation on the balcony, when Alma says "Do you really think it's possible there's a fifth Horseman?", the left side (right side from camera view) of her jumper shows a couple of inches of her shoulder. But in the following shot, her jumper now covers up the left side of her entire shoulder.
When the Horsemen find the blueprints, as Henley says "I really want to meet them", she is standing about a foot away from Daniel. But in the next shot, she's suddenly standing several feet away from him.
In the 5 Pointz, Queens scene where three of the four horsemen project themselves on the walls of the building, you see a cut to them standing in front of their three cameras. The cameras are pointed closely at their faces and yet you see a complete body shot of each one on the walls.
After Henley finishes her trick and the camera pans over to her, just before the camera stops panning, there is a blonde woman with short hair and tree patterns on her dress visible in front of her to the right (or viewer's left). But as it cuts to a wide angle, that same woman is suddenly behind her.
In Merritt's first scene, he walks over to a man and reads his mind. Just as the man says "Look, it was a business trip", he is looking at Merritt. But in the next shot, he's suddenly looking at his wife.
Once the teleport device is unveiled, Merritt walks the banker over to the device. During this shot, Henley is on the right side of the device, walks over to it, and begins to reach down for something, but by the next shot, she is right back where she started and not reaching down for anything.
After Dylan is transported under the stage to the Horsemen's fake vault, Alma, Thaddeus and Thaddeus' assistant open the vault door after walking down the stairs. Thaddeus walks in and Dylan asks "What was with the helmet?" Thaddeus then exits the shot after Dylan finishes the line, but within a split second, Thaddeus has suddenly moved half way across the room with no time to do so.
When Merritt mind reads Daniel to find out he is a "control freak", Henley is behind Daniel. Then she is standing next to him, then back to behind him where she takes a step forward to be right next to him.
As Merritt puts the wife to sleep, the first shot shows a woman visible in the background leaning against one of the columns then takes a step forward to talk to someone sitting. In the next shot from further away, the woman in the background is no where to be seen, then when the camera goes back to Merritt and the couple, the woman is there again. The further away shot had nothing with the camera angles.
In the flashback of the Horsemen programming the banker's mind, the banker is shown walking down a flight of steps and Daniel is shown throwing and catching some poker chips. He is first shown throwing two poker chips in the air, then in a close-up, it is only one poker chip being thrown into the air.
When the Horsemen discover the "Now You Don't" card, the first shot shows the edge of the card to be resting on the lining on the floor. When Daniel picks the card up, almost half of the card is shown to be resting on the lining in the floor. The same goes for the rose.
When Jack tackles Agent Fuller in the apartment, he grabs his jacket, pulls it down, and shoves the sleeves into the garbage disposal. When Jack turns on the disposal, some sort of utensil holder falls into the sink on the left side. After Fuller yells out "Dylan" after spitting out a wet cloth forced into his mouth, a shot of the sink is shown and the utensil holder has suddenly shifted slightly to the right. Fuller couldn't have moved it since his arms were stuck in his jacket and his jacket was stuck inside the garbage disposal.
During the fight at the apartment, Jack grabs Dylan's gun with a belt and throws them at Agent Fuller, trapped in the sink's garbage disposal. When Fuller is hit, his head is thrown backwards slightly. In the shot following, his head is suddenly facing forwards. This is only visible for a split second, so you'll need to be quick in order to see it.
When Dylan and Alma are having lunch with Thaddeus Bradley, as Thaddeus says "My first show, I revealed all of his tricks", Alma is looking straight at him with her head slightly shifted to the left. In the next shot, she is looking down on the table, with her head shifted to the right. Theatrical version only.
In a flashback of the money being stolen from the vault, the card with the signature is notably in front of the Las Vegas ticket. The next shot where the employee enters the vault, now shows the ticket on top of the card if you look very closely.
Just after the Horsemen make Tressler broke, Arthur shouts "Did you do this?" Merritt, Jack and Henley separately talk to him after he says this. At the start of Henley's line, her arms are by her side. But in an instant close-up of Henley, her hands are suddenly raised.
When Alma first talks about Lionel Shrike's card trick, as she says "Then he goes to a tree that's been there 20 years", she is seen quickly lowering her head. Camera cuts and her head goes back to being raised.
After Fuller states to Dylan that the Horsemen have tracking bracelets, Dylan is on the balcony looking at a crowd. He is then joined by Alma and he turns his head to her. In the following shot from behind the two, Dylan is now suddenly looking at the crowd.
In New Orleans, Alma shows Dylan a book on Lionel Shrike. When the camera is front of her, she is holding the book with her hand at the top. In the reverse angle, her hand is suddenly holding the bottom. We can't really see but in the reverse angle, her hand isn't placed on the top, whereas in the previous shot her hand was placed on the top, so her hand definitely isn't in the same place.
When Henley is first looking at 45 East Evan Street, her tarot card is in her hand, pushed up against a cup of coffee. By the time she meets up with Daniel, the card is no longer pushed up against the coffee cup, but instead in one of the other fingers. She couldn't have moved the card, because her bag was in her right hand and the coffee was in her left.
When Dylan and co are in the truck, finding out that his phone has a bug in it, Dylan tells the female agent to put the bug back in his phone. As Dylan says "They don't know that we know about the bug", Alma is looking at Dylan. Next shot, she's suddenly looking at the female agent putting the bug back in his phone.
As Daniel, Merritt and Henley are in the elevator, the first shot of the elevator (exterior shot) shows Merritt standing a couple of inches away from the wall. A couple of shots later, Merritt is suddenly standing in the corner of the elevator.
When Thaddeus goes to the Horsemen's room, Daniel begins to do a card trick on him. The other Horsemen go to stand up next to him. As this happens, Henley holds a rabbit with the rabbit held straight along her arms, then the rabbit's head is held higher than the rest of its body, then back to being held straight along her arms. Extended version.
On the plane ride to New Orleans, Dylan tells Alma the Horsemen were a bunch of street magicians a year previously. As the shot ends, Alma has her head turned 90 degrees facing Dylan. Yet in the side angle, her head begins to turn that position.
In the scene where Thaddeus explains to Dylan and Alma the Horsemen's first trick, he asks his assistant to get the teleportation helmet for Dylan. As Thaddeus' assistant reaches down for the helmet, Dylan is looking at Thaddeus, not smiling. In the next shot, Dylan is suddenly looking at Thaddeus' assistant with his head turned 90 degrees, now smiling.
When Merritt begins his first magic trick, he puts a woman in "sleep" and places her head on his shoulder. In the first shot, her head is turned 90 degrees to the left. But in the next shot from a distance, her head is on his shoulder but isn't turned an inch. Her head goes to being turned 90 degrees once again in the next shot. Then back to not being turned when he lets go of her.
Just after Daniel and Henley put the rabbit in the box at the New Orleans show, Daniel closes the lid to the rabbit box. Daniel then says "If you'll say the magic word?" to Henley. Henley at this point, has both of her hands on her hips. Then her hands in front of her belly held together. The shot after that shows her hands are behind her back.
When Henley walks Arthur Tressler onto the stage, she says "Now Art, did you fill out your envelope?" During this shot, there is light visible on the back of her jacket. But in a closer shot of the two, the light on the back of her jacket is no longer there.
In the scene where Thaddeus goes into the Horsemen's room to wish them good luck at the New Orleans show, Jack is seen moving from one side of the couch to the other when Merritt says "Do you mind if I do a quick read on you?" Two shots after this, he is seen moving to the other side of the couch a second time. Extended version.
The shot before Alma goes to show Dylan the book on Lionel Shrike, she turned 90 degrees away from him. When she shows him the book in the next shot, she is suddenly turned to face him without any time to do so.
At the Las Vegas show, Daniel says to the French banker "If you could sign your name. In English if possible." The next shot shows Henley walking around the stage in the center. But by the next shot she's suddenly standing at the edge of the stage.
In the scene in which the magicians all meet each other, Jack shows his card to the other three magicians. In this shot, Henley's card is already raised. In the following shot, she goes to raise her card a second time.
After the Horsemen escape, Dylan is drunk in a bar having an annoyed conversation with Alma. From the shots in front of Alma, there are several strands of her hanging over her left ear. From the shots behind Alma, there is only one strand of hair hanging over her left ear.
After Alma states how Lionel Shrike performed his card trick, Dylan replies "The card is in the tree." Alma, visible to the left of screen, has her head perfectly still after he says this. But when she says "It was in the tree for 18 years" in the next shot, her head is suddenly leaning forward a few inches.
After Daniel makes the rabbit "disappear" from the rabbit box, Henley begins to look "shocked" and raises her hands halfway. From one angle, her hands are turned 180 degrees, but from a reverse angle, her hands haven't been turned an inch.
When the horsemen's names are announced at the New Orleans show, Daniel points out that they would like to dedicate the performance too. Henley then states that it is Dylan and Alma they are dedicating it too. In the reverse angle where Henley starts saying the line, both of her arms are by her side. But when the shot cuts to a shot of Henley, her left arm is suddenly raised. Extended version.
Whilst interrogating Daniel, Alma asks him "If you had nothing to do with it then how did the playing card get into the vault?" At the end of this shot, Daniel raises his head upwards. In the next shot, he is suddenly looking forward at the table.
After Tressler's bank account cheque lowers $280k, Henley says "We have a confession to make." In this shot, Jack is in the background almost in darkness, then in the next shot, as Jack says "We lied about something", Jack is suddenly covered in stage light.
When the French banker is called onto the stage, Daniel points out that they wouldn't be there for Arthur Tressler. As he says this, Henley is visible to the left of screen with her hands by her side. Yet from the next shot, her right arm is suddenly raised pointing at Arthur.
When Thaddeus shows his wine changing color trick, Alma goes to drink from the glass. In one shot, the glass is right next to her mouth, but in the following shot, the glass is now on her lap. Extended version.
When Thaddeus shows to Dylan and Alma the first Four Horsemen's trick, when Dylan is in the teleport device, as the cloth is being lowered down, he is seen looking straight forward at a 12 o'clock direction. Shot cuts and he is instantly looking downwards.
At the start of the plane scene to New Orleans, Merritt says "Allow me to make plain what we've both been thinking." At this moment, Merritt is resting on a pillow with a T sign stitched onto it. Merritt is first shown to be resting on the T, but a couple of shots later, Merritt is suddenly on the other end of the pillow.
When the Horsemen show each other their tarot cards, Daniel states that he is The Lover and Henley jokingly coughs "Three minutes" and Merritt states that he is The Hermit. Merritt is then shown turning his head to Henley looking annoyed and Henley is looking at Merritt. Next shot, she's looking at Jack.
At the start of the scene where Dylan and Alma are having lunch with Thaddeus, Dylan asks Thaddeus "So you were a magician first?" At the end of the line, he lowers his hand, but by the next shot, his hand is suddenly raised, placed on his chin. Theatrical version only.
When Merritt starts "sensing" on Daniel, Henley is heard laughing and Daniel turns to her, then he turns back to Merritt. This shot shows Merritt's only arm in shot completely lowered. Next shot, his arms are both raised.
When Dylan lands in the fake vault, he lands right next to the grey thing where all the money was placed on. When Alma, Thaddeus and Thaddeus' assistant enter the vault, he is suddenly standing almost a few meters away from the grey thing where all the money was placed. This has nothing to do with the camera angles because his hand landed on the grey thing as he landed in the vault.
As the wife in the cafe attempts to take the dollar note from Merritt, Merritt's arm is shown to be raised as he holds the note. When Merritt says "If you can say you're name, you can have it", his arm is still raised holding the note, then as the wife begins to say her name in the shot following, his arm is suddenly lowered.
When the banker is doing his Philharmonic, Dylan tells Alma to tell him to stop and Alma then replies "No, I can't. You just have to let him finish his movement." In the reflection of the mirror behind them, we can see Dylan is looking at Alma. Next shot, Dylan is suddenly looking at the banker.
As the Horsemen are searching the apartment, just before reaching the living room, Jack states that it is freezing. From the reverse angle, Jack is shown looking to the right. Next shot, he's suddenly looking forward.
During Jack's first scene when he challenges the audience to figure out his spoon trick, when he has lifted the winners watch and wallet, the scene clearly shows the boat quite far from the pier and moving further away as seen by the trail from the propellers. Yet when Jack makes his escape, the boat is back at the pier and only just pulling away, giving him time to jump back to land before he can be caught.
Agent Rhodes is standing in a pavilion under the 59th Street Bridge after the car accident and talking on his cell phone with Thaddeus Bradley. One minute later, at the end of the conversation, the same bridge is seen a couple of miles in the background.
After their final act, when standing in Times Square, one of the jumbo screens is displaying a headline that says The Four Horsemen disappeared after running off a building. Only three of the four Horsemen were present for that event.
The shot before Daniel throws the cuffs onto Dylan's wrists, he lifts his arms beginning to throw the cuffs on his hand. In the next shot, his arms are back on the table ready to throw the cuffs a second time. This is only visible at the very start of shot so you have to be quick to see it.
After arriving at 5 Pointz, someone tries to find the combination for the safe and it is revealed to have had a green handkerchief attached to the rear end. Dylan then pulls on the handkerchief and keeps pulling on it to reveal more colored handkerchiefs until it stops and a timer is heard ticking. When the clicking sound is heard, Dylan is shown holding onto the knot between a purple handkerchief and a blue handkerchief. The shot then cuts to Agent Cowan saying "What is this?", but when the shot cuts back to Dylan, he is suddenly holding the knot between a blue handkerchief and a yellow handkerchief. Then in the next shot, his entire hand is held onto the blue handkerchief.
When Merritt mind reads the cafe guy, he "picks up a woman's name" and starts saying "A - B - C - D - E - F - G - H - I - J - Janet." In the rapid shot of the man's mouth when Merritt says this shows his head in fixed position. But in the rapid shot of the man's eyes when Merritt says this now shows his head shifted a bit.
After hypnotizing the woman in the cafe, Merritt goes over to her husband and begins to mind read him. Merritt begins to say "I'm picturing, don't tell me" and the man replies "Of course." When the man finishes saying "Of course", his head is shifted to the right about 40 degrees, but from the following reverse angle, his head is only shifted about one degree.
At 0:28:32 Atlas rises from his chair to swap the handcuffs. Freeze-framing through the edit reveals Atlas is shown face-on releasing his handcuffs, and in the next shot, his hands are back on the table with the handcuffs still fully on. The running of the film therefore jumps backwards in time for a fraction of a second.
The person who delivers the card to Henley clearly states the amount of preparation necessary for the events of the film. It is reasonable to assume that the card she received was waterproof. (In fact, a commercially available brand of playing cards is made in real life that can be used underwater.)
When the Four Horsemen are setting up the giant mirror hiding the safe, you can see their reflections in the mirror. However, any of the FBI agents close enough to the mirror could look up and see their reflections as well, ruining the trick and proving the safe was still in the warehouse.
While it's possible to project a "hollow" effect on the side of a building, it must be carefully calculated to account for the viewer's position, and only works while the viewer is in that spot. If the viewer is in wrong position, the perspective of the projection and the shape of the building no longer match and the illusion is broken. Yet in the final trick, the "hollow building" effect is seen from above, below, in front, left, and right, simultaneously, and moves with the movie camera. The audience would only see a weird, skewed image of the building.
(at around 1hr 23mins) Projections are made onto the side of a building. This is onto walls heavily covered with graffiti, and lots of windows. Yet the projections appear as if they are onto a clean white surface, not the actual walls and windows.
The goof items below may give away important plot points.
Dylan Rhodes reveals everything to Alma Dray in the last scene of the film. However his intention, after decades of preparation, was revenge on Thaddeus Bradley for the death of his father. By confessing all to Alma, he's ultimately freeing Thaddeus, since the American newspaper and her testimony combined with Dylan's disappearance from the FBI would be enough to free him.
In the carousel scene, right after Dylan says,"Welcome to the eye," he grabs a pole and gets on the carousel. In the next shot of him he is holding a pole connected to a carousel horse, but the shot after that he is holding a pole with no carousel horse.
