Continuity mistake: When Diamond drags the bad guy out of the water, the hunting dog that's been sitting on the dock barking at them disappears between takes.
Richard Diamond, Private Detective (1957)
1 continuity mistake in Escape from Oak Lane
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.
