Richard Diamond, Private Detective (1957)
1 visible crew/equipment mistake in Juvenile Jacket
Starring: David Janssen
Revealing mistake: The car that goes over the cliff is at least ten years older than the car it's supposed to be - the 1957 Plymouth Fury that Diamond was driving. It's obviously old 1940s stock footage.
