Corrected entry: When the banker's goon tells Jake to look at Lily, after hitting him to the ground, he repeatedly points the gun at both of them. A professional hitman would surely be a bit more careful with his weapon. He repeatedly stabs at the air with it to emphasise a point, while it is aimed at the girl who he is supposedly protecting.
Corrected entry: When we first meet Andy Garcia, he makes a big deal about always wearing the same tie which Ed Burns sent him. In the next scene, the tie has changed colours.
Correction: The lighting makes the tie look darker in the cafe, and it is shiny which doesn't help, but Gunther does wear the same tie throughout.
Correction: A character pointing and shaking his gun at people he is going to shoot is not a mistake.
