Visible crew/equipment: While Anne moves around the palace, trying to escape, she enters a room filled with mirrors. But in one mirror, bottom left, there is a shadow, like someone - a crewman, perhaps - trying to keep out of the shot, but not succeeding.
Roman Holiday (1953)
1 visible crew/equipment mistake - chronological order
Directed by: William Wyler
Starring: Gregory Peck, Audrey Hepburn, Eddie Albert, Hartley Power
Continuity mistake: When Ana wakes up in Joe's room in the morning, Joe's tie goes from being tucked into his belt, to being out, and back in again in successive shots.
Princess Ann: I could do some of the things I've always wanted to.
Joe Bradley: Like what?
Princess Ann: Oh, you can't imagine. I-I'd do just whatever I liked all day long.
Trivia: When Gregory Peck puts his hand into the Mouth of Truth and withdraws it (hand tucked into sleeve) the scream that Audrey gives is real. The prank was unscripted, but the reaction so perfect that it was left in.
