Visible crew/equipment: When Audrey and Diamond leave the dance club, a microphone shadow sweeps across the top of the door as it closes.
Richard Diamond, Private Detective (1957)
1 visible crew/equipment mistake in Family Affair - chronological order
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.
