Man About the House is a British sitcom created by Brian Cooke and Johnnie Mortimer. It starred Richard O'Sullivan, Paula Wilcox, Sally Thomsett, Yootha Joyce and Brian Murphy. Six series were broadcast on ITV from 15 August 1973 to 7 April 1976. The series was considered daring at the time because it featured a man sharing a London flat with two single women. The show was made by Thames Television and recorded at its Teddington Studios in Greater London. It is regularly repeated on ITV3.
