Continuity mistake: During Sullivan and Maguire's gun fight at the hotel, between the fifth and sixth shot Maguire takes at Sullivan, a bullet imprint instantly appears on the trunk Sullivan is taking cover behind, in the top right corner.
Continuity mistake: When Jude Law is first talking to Tom Hanks in the diner, he orders a cup of coffee. They talk for about 30 seconds with the camera going back and forth between Hanks and Law. In one shot, there's nothing on Jude's table, then in the next shot of him he has a cup of coffee in front of him.
Suggested correction: If you listen carefully when the camera is on Tom Hanks, you can hear the sound of the cup and saucer being put on the table.
I was actually going to enter this. I agree with the original mistake. You do hear the clink of the cup being put down, but everything happens just a little too fast. We don't hear the waitress approaching, the camera is off Jude Law for no more than 2 seconds. When it comes back to him, the coffee is placed, and he is pouring sugar in and stirring.
