U.S. Marshals (1998) - 5 major mistakes

Factual error: In the scene where Tommy Lee Jones goes back to Wesley Snipes' hotel room and finds Robert Downey Jr. about to execute Snipes, RDJ turns his gun on TLJ and pulls the trigger. We hear the click of the hammer dropping and, in frustration, RDJ pulls the trigger again, and again, we hear the hammer dropping on an empty chamber. Glock pistols are not able to be fired unless the slide moves all the way to the rear, so after the first shot, RDJ would have had to work the slide to be able to pull the trigger again. He didn't do that, though, so there should not have been a second click.

Visible crew/equipment: When the dark car is backing up to park at the entrance of the cemetery and keep watch, you can clearly see the cameraman in the reflection of the right side rear window.

Continuity: Jones is following the guy with the green cap in a yellow cab into the graveyard. For one shot the hubcaps on the cab are missing. The next shot they are back.

Continuity: In the scene where they are talking to Snipes girlfriend. Downey says he killed them with his bare hands and shows her a picture of a guy shot twice in the chest.

Continuity: When Wesley Snipes is being questioned about the double homicide in New York, the detective says that it occurred in December. When Tommy Lee Jones is viewing the tape of the double homicide from the UN garage security cameras, the date from the video tape clearly says January 12th.
