The film was based on a West End play by Andrew Macrae about Englishmen travelling in Europe and the problems experienced by them due to post-war currency restrictions. It premiered at the Criterion on 2 June 1948 starring
Yvonne Arnaud and produced by
Hugh Beaumont; it was a smash hit, running for two years.
Clement Attlee saw the play while he was Prime Minister.
Sydney Box bought the film rights while head of Gainsborough Pictures. The film starred John McCallum and Googie Withers, who had recently married. "We think, it Is an excellent idea to work together," said John. It was the first of a three-picture contract Withers signed with Sydney Box. The job of directing was given to Ralph Thomas, who had just made two comedies for Box,
Once Upon a Dream and
Helter Skelter. John McCallum came down with
jaundice during filming and had to take a week off. This caused filming to be suspended for a week, costing the production £12,000. However the film was completed half a day under schedule. ==Release==
