The Hill (1965)

Continuity mistake: When the commandant comes into the prison in his jeep just after the Sergeant Major says to King: "Then you can drill with these men and you can dance over that hill with them," he takes out his pocket watch from his LEFT breast pocket to check the time the commandant arrived Up to this point, and just before this shot, his pocket watch has always been in his RIGHT breast pocket, where it remains for the rest of the film.

SSgt. Williams: Don't talk back, you different-coloured bastard.
