At the Buy/Sell auction, Zenigata tells Commander Narong that he'll "nail Lupin". Lupin is not his target at this point in time; it's Michael and Pramuk.
Edward Lam is referred to as "Lee" on the first page of Dawson's book.
When Lupin is using the lip-reading application on his sunglasses to listen to Michael and Pramuk's conversation, Michael's line "I've waited a long time for this" is rendered in onscreen without the indefinite article "a".
A idle, parked car is visible on the freeway behind Royal and Saber's Hummer after the car fight.
The "champagne" the gang drinks before leaving for The Ark is clearly sparkling water.
When Zenigata presents Lupin's file to the Hong Kong police, his name is presented as "Lupin the 3rd". Although this is a common spelling of the character's name, it is not the formal form ("Lupin III") that would likely be used by an organization such as Interpol.
The Crimson Heart of Cleopatra is clearly made out of plastic.
The buy/sell auction of the necklace and ruby of the Crimson Heart of Cleopatra - items which are publicly known to be stolen property - is an illegal action in and of itself, turning the audience into (as one critic has put it) "a room full of witnesses for illegal dealings". Therefore, Zenigata should not need Lupin to "steal" the Crimson Heart to provide proof for Michael and Pramuk's illegal activities, and his throwaway line directed at Miss Vee referencing this fact does not make it any more logical.
Lupin's Fiat 500 does not take any visible damage during the car fight with Royal and Saber despite numerous collisions and shots being fired.
Why should Lupin and Fujiko be surprised at the revelation that Pramuk killed Edward Lam? It seems unlikely, if not impossible, for Dawson to skip out on such a detail in his book, the information in which at least Lupin is familiar with.
When did Lupin get an opportunity to give Miss V the fake Crimson Heart? He is clearly holding the real one when she and Pramuk's men capture him at gunpoint.
