Revealing mistake: In the bull ring scene, in the close up shots it's Raquel Welch, in the pulled back shots it's obviously a stuntman in drag with her voice dubbed in.
Fathom (1967)
1 revealing mistake - chronological order
Directed by: Leslie H. Martinson
Starring: Raquel Welch, Anthony Franciosa, Richard Briers, Ronald Fraser
Continuity mistake: In the plane chase at the end, Raquel Welch's plane goes into a bad spin (outside shot). We then cut to the inside of her plane, and the background is just rocking slightly from side to side.
Peter Merriwether: Fathom, eh? I never met a Fathom. Where did you ever get a kinky name like that?
Fathom Harvill: First initials for uncles - Freddy, Arthur, Tom, Harry, Oscar, Milton. They were all rich, and Papa wasn't taking any chances - unlike me.
