The Constant Husband

The Constant Husband is a 1955 British comedy film, directed by Sidney Gilliat and starring Rex Harrison, Margaret Leighton, Kay Kendall, Cecil Parker, George Cole and Raymond Huntley. The story was written by Gilliat together with Val Valentine, and the film was produced by Individual Pictures, Gilliat's and Frank Launder's joint production company. Because the film got caught up in the 1954 bankruptcy of British Lion Film Corporation, it was not released until more than seven months after it had been finished and reviewed by the British Board of Film Censors.
