Continuity mistake: In the climactic boat scene when Kevin Pollack runs back from the boat to the van full of money he shoots the man standing by the back of the van. Pollack is then shot in the back as he looks at the money in the back of the van. When Kevin Spacey returns to the van later in the boat scene, we see Pollack's dead body lying on the ground behind the van, however the dead body of the man who Pollack killed has disappeared.
Trivia: The way none of the characters can keep a straight face when reading out the card in the line up was not scripted, but resulted because the cast had had a rather good lunch prior to filming, which included some wine, and were unable to get through what was scripted as a serious scene with straight faces, because of the nature of the scene - supposedly very serious, but they were being asked to utter this rather absurd (and obscene) phrase.
Trivia: In the lineup scene, when the officer asks Benicio del Toro to repeat the phrase "in English, please," the voice is actually the director. That line was not scripted. The director actually wanted to retake Benicio's line because he didn't think it was understandable. He ended up keeping it because he thought it was funny.
Question: While in interrogations Kujan is asking Verbal why Keaton told him to stay back while they were robbing the boat. After a back and forth conversation between them about it they come to the conclusion that it is because Keaton is Kaiser Sose and he wanted Verbal to be his will. However we come to find out this is not true, and Verbal is actually Kaiser Sose, so why did Keaton have Verbal stay back?
