Visible crew/equipment: When Donna jumps off the bridge, her falling body is a dummy/mannequin of some sort - its arms are stiffly by its side, and it has no face. (00:01:54)
Baywatch Nights (1995)
1 visible crew/equipment mistake in Heat Rays
Starring: Angie Harmon, David Hasselhoff, Eddie Cibrian
Factual error: Donna jumps off the bridge (which is relatively low down), into shallow water. She then narrowly avoids being hit by a huge ocean liner. There's no way such a huge ship would be in such shallow water - for starters, it couldn't cross under the bridge, being far too big. (00:03:12)
