Fehler, die von Charakteren gemacht werden (möglicherweise Absicht der Filmemacher): Tom claims to have invented the paper cup sleeve when in reality it was invented by a man in California named Jim Chelossi.
Filmfehler: Opening Scenes: when showing the Brooklyn Bridge/Manhattan Bridge with Verizon building in the background, the picture is flipped. The Brooklyn bridge is SOUTH of the Manhattan bridge when looking at Manhattan. You can barely see the Verizon logo spelled backwards.
Faktische Fehler: In the scene where Tom calls Hannah, she says it is 3am in Scotland. With the 5 hour time difference, that makes it 10pm in New York, yet light is shining through Tom's window.
Anachronismus: In the opening party sequence, a logo sheet can be seen hanging on Hannah's dorm room door displaying various Cornell logos and insignia, including the redesigned crest logo, which wasn't in use until 2004. In 1998, the official Cornell logo was still the oft-mocked "Big Red Box", which was frequently criticized as looking too much like a clone of the square J.C. Penney logo.
