Kenneth Charles Williams was a British actor and comedian. He was best known for his comedy roles and in later life as a raconteur and diarist. He was one of the main ensemble in 26 of the 31 Carry On films, and appeared in many British television programmes and radio comedies, including series with Tony Hancock and Kenneth Horne, as well as being a regular panellist on BBC Radio 4's comedy panel show Just a Minute from its second series in 1968 until his death 20 years later.

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.
