Carry on Camping (1969)

Revealing mistake: Although the movie 'Carry On Camping' is supposed to have been set in the summer time, it was actually filmed in November 1968, during a spell of very cold weather. You can actually see the cast's breath in the cold air at some points. The field in which the famous "flying bra" sequence was shot was so muddy, that the mud had to be sprayed green to make it look like grass.

Mr. Short: Miss Dobbin, what's the meaning of this?
Miss Dobbin: I'm sorry sir but the gentlemen kept touching things.
Charlie Muggins: Yes she was showing me how to stick the pole up.

Trivia: Although Amelia Bayntun plays Joan Sims' mother in the film, she was only 11 years older than Sims.
