Carry on Regardless (1961)

Continuity mistake: When the team are in the derelict house, Mike Weston turns the right hand tap on and no water comes out. When Handy turns the stopcock on the water comes out of the left hand tap.

Trivia: The drink that Joan Sims drinks at the wine tasting party was actually neat gin. Director Gerald Thomas switched the non-alcoholic drink in Joan's glass for real claiming that he wanted a good 'reaction' shot.
