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.
Continuity mistake: When Sid and his friends arrive at the camp site and they are talking to the man putting up the sign, Mr Fiddler come back with the letter p, so the sign will say "all passes must be shown". At the end as Dr. Soaper and matron go after the flowerbuds lorry as they go past the sign it says "all asses must be shown".
Continuity mistake: In the scene where Mr & Mrs Potter are cycling to the holiday camp, you can see that about 100yards behind them, a white car is parked on the right hand side of the road. In the next shot, they pass by Mr Muggins and the car suddenly appears immediately to their right. They seem to be back where they started. (From DVD viewing).
Continuity mistake: In the scene where the girls are fighting in the school, they stop when they hear Matron. After Matron leaves the room, Babs puts the line of wool around the other girls neck.There is a girl standing on the right of the TV but in the very next shot, she is sitting.
Continuity mistake: During the infamous scene where Barbara Windsor loses her bikini top, in the background is a man standing in front of a Yellow Tent. In the next couple of shots from the same camera, the tent has disappeared and now there are different people standing in the background.
Continuity mistake: During the scene when Sid James is tying up the necklaces of the hippies at the rave-up, one of them he ties up is a blonde haired man with a striped shirt and brown jacket. But when we see "The Flowerbuds" performing a little later on, this man is no longer tied up - he is now dancing with the other hippies.
