Frenzy (1972)

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.

Continuity mistake: When the potato truck with Rusk searching the woman's dead body for his R lapel pin is traveling on the highway, the tailgate is down which allows potatoes to fall out. As the police car passes the truck, the tailgate is up. When the truck driver stops to check the tailgate, the tailgate is again down.

Continuity mistake: The amount of fish soup the inspector has in his plate changes between shots. The contents of the plate also change and sometimes we see different fish.

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.

Mrs. Oxford: Woman's intuition is worth more than all those laboratories. I can't think why you don't teach it in police colleges.

Robert Rusk: I don't know if you know it, Babs, but you're my type of woman.

Robert Rusk: Don't forget, Bob's your uncle.
