Visible crew/equipment: When the lizard gets away, and is riding in the elevator, it is shown alone in there. In the next shot from the back of the lizard, you can see the shadow of the handler or crew-member's head moving around on the top of the lizard.
The Freshman (1990)
1 visible crew/equipment mistake - chronological order
Directed by: Andrew Bergman
Starring: Matthew Broderick, Marlon Brando, Penelope Ann Miller, Bruno Kirby
Continuity mistake: About five minutes before it ends,Bruno Kirby is sitting down at a table talking to Maximillian Schell and others. He loosens his tie, which lays to his right. The camera cuts away from him, then back to him, and his tie is on the left.
Carmine Sabatini: I'm getting too old for this nonsense.
