Carry On at Your Convenience is a 1971 British comedy film, the 22nd release in the series of 31 Carry On films (1958–1992), and was the first box office failure of the series. This failure has been attributed to the film's attempt at exploring the political themes of the trade union movement, crucially portraying the union activists as idle, pedantic buffoons which, apparently, alienated the traditional working-class audience of the series. The film, known as Carry On Round the Bend outside the United Kingdom, did not return full production costs until 1976 after several international and television sales. The film features regulars Sid James, Kenneth Williams, Charles Hawtrey, Joan Sims, Hattie Jacques and Bernard Bresslaw. It features Kenneth Cope in the first of his two Carry on appear
