Carry On is a British comedy franchise comprising 31 films, four Christmas specials, a television series and stage shows produced between 1958 and 1992. Produced by Peter Rogers, the Carry On films were directed by Gerald Thomas and starred a regular ensemble that included Sid James, Kenneth Williams, Charles Hawtrey, Joan Sims, Kenneth Connor, Peter Butterworth, Hattie Jacques, Terry Scott, Bernard Bresslaw, Barbara Windsor, Jack Douglas, and Jim Dale. The humour of Carry On was in the British comic tradition of music hall and bawdy seaside postcards. The success of the films led to several spin-offs, including four Christmas television specials (1969–1973), a 1975 television series of 13 episodes and three West End stage shows that also toured the United Kingdom.
