I'm All Right Jack (1959)

Continuity mistake: When Stanley is shown around the cake factory he takes his hat off and puts it on a conveyor belt and it is carried into a machine and covered in icing. But in the scene before this with the supervisor saying "and this is the enrobing chamber" you can see his hat come into shot on the conveyor belt already. In the next shot he still has his hat on and only then takes it off and puts it onto the conveyor belt. (00:13:08)

Major Hitchcock: We've got chaps here who could break out in a muck sweat merely by standing still.
