Murder at 1600 (1997)

Continuity mistake: Towards the end of the movie, when all three are crawling through the Lincoln Tunnel, they are almost waist deep in water. Yet, the Secret Service lady's jeans change from dry to wet and back again. The same when she is chased back through the tunnel, her and the Secret Service guy's trousers are dry.

Christoph Galuschka

Other mistake: When they look at the negatives on the boat there is the typical holes at the top and bottom of the negative. Then they magnify a part within the picture. After they look at the magnified part, but the holes are still there.

Ronnie Bischof

Continuity mistake: When Snipes and the secret service lady are in the VCR store playing the hidden camera footage, it goes from a shot of the employee and then back to Snipes again and again. You can see that the hidden camera footage stays in the same spot during these shots.

Trivia: Shortly after the midpoint of the film, when Regis and Spikings sit down for a drink in the living room. We see an extreme close-up of Spikings saying "loneliest job in the world" as he takes a sip. There is a tiny grinning skull / demon face in the ice in his glass.

Detective Harlan Regis: I think the president's gonna become an international suspect.

Agent Nick Spikings: Do you what it means to be a team player?
Nina Chance: Sharp-shooting isn't a team sport.

Detective Harlan Regis: This is Carla's tape from her answering machine.
Nina Chance: Yeah.
Detective Harlan Regis: Well, how'd you get it?
Nina Chance: I stole it.
