Carry On England (1976)
1 plot hole - chronological order
Directed by: Gerald Thomas
Starring: Kenneth Connor, Judy Geeson, Windsor Davies, Patrick Mower
Continuity mistake: In the scene where Captain S. Melly and Sergeant Major "Tiger" Bloomer are testing the air raid siren, the handle of the siren gets caught between Bloomer's legs and you can see he is not wearing his headphones, but in the next shot he suddenly has them on.
Trivia: Kenneth Connor's line, "I've been regular for eighteen years", is an in-joke about his time in the "Carry On" films. He made his debut in 1958, and when the film was released in 1976, he was in the films for eighteen years.
