Deliberate mistake: This has the old T.V. show style "it was 6 a.m. on January 7th we ... " beginnings to the scenes. Pay attention to those times and dates. They're not even close to being in sequence. I mean days, not just times.
Dragnet (1987)
1 deliberate mistake
Directed by: Tom Mankiewicz
Starring: Tom Hanks, Christopher Plummer, Dan Aykroyd, Harry Morgan
Continuity mistake: When their car blows up, look in the background and you can see Friday practically kneeling on the ground, and Streebeck falls over completely. Within two seconds (and a couple of cuts) they're both standing up, fully alert with their guns out - Friday might just have managed it at a push, but Streebeck went from face down on the pavement to upright far too quickly.
Narrator: Ladies and gentlemen, the story you are about to see is true. The names have been changed to protect the innocent. For example, George Baker is now called Sylvia Wiss.
