Continuity mistake: Agent Rich Harmon applies the good old dating strategy of telling a sob story about his childhood. Sheri's hair moves from all in front of her right shoulder, to all in front of the left shoulder (and she is also not holding/ holding her glass). (00:41:10)
Continuity mistake: Thanks to a well-placed compliment about her "backyard", Harmon scores an instant date with the mayor's daughter. They go from the police station to a bar, and somehow en route she has changed hairstyle entirely. (00:40:30)
Continuity mistake: Chief Speed and the mayor are talking; Mr. Anderson says "C'mon Clarence, there's a lot at stake this weekend." Clarence Speed is holding a black ID. In the next shot he's holding a pink lighter, the ID is in another spot on the desk. (00:37:20)
Continuity mistake: When David approaches the homeless guy on the stretcher, he's lying with his hands under the sheet in the first shot, arms crossed on top of the sheet in the next. (00:36:35)
Revealing mistake: The mayor's daughter Sheri hits the villain with a punch that the policemen call "a haymaker" and that hurt her hand. It was anything but; just a bad fake movie punch. (00:30:10)
Continuity mistake: After a close-up on Wildman Jack Armstrong, we see a homeless guy eating with a spoon. He turns around, and in the next shot while still being turned around his left hand traded the food with a flaming stick. (00:28:20)
Continuity mistake: David arrived home late for his birthday and his wife is mighty irritated; she serves him on purpose a couple of completely charcoaled steaks. However, the food looks completely different in the close-up (there's much less of it, for starters). (00:15:45)
Other mistake: David's wife is looking inside the microscope at what she describes as a protein found in the saliva. It does not quite look like a protein, and in fact it's a reused (it's exactly the same) microscope image from the previous movie, where Marisa identified it as" a section of the pituitary glans of a Lhasa Apso." (00:12:00 - 00:51:25)
Continuity mistake: David goes downstairs and finds out about his surprise birthday party. The tape recorder and the other objects on the table change position between shots around the ugliest cake ever. (00:05:25)
