Other mistake: When Lorry driver goes around the back to put the door up, you can see the type of lock, but when they zoom in, it's like a peg you slot in, then when they zoom out it's the other type of lock. (01:19:16)
Frenzy (1972)
1 other mistake - chronological order
Directed by: Alfred Hitchcock
Starring: Billie Whitelaw, Alec McCowen, Anna Massey, Barry Foster, Jon Finch, Barbara Leigh-Hunt
Continuity mistake: Watch the bar scene about ten minutes from the start of the film. The barmaid is holding 2 pints, but note how the froth disappears when the shot changes as they are placed on the bar.
Robert Rusk: Don't forget, Bob's your uncle.
Trivia: Hitchcock's cameo can be seen three minutes into the film, just after the opening credits. As Sir George espouses the virtues of a clean river, Hitchcock can be seen in the crowd wearing a bowler hat.
