The film was a co-production between Gainsborough Studios and UFA initiating a decade-long series of co-productions which ended with the rise of the Nazi Party in the 1930s. The film was based on the 1923 novel The Blackguard by Raymond Paton, and shot at Studio Babelsberg, in Potsdam near Berlin, the first time a Gainsborough film was shot abroad. The film was one of a number of films made in this genre during the 1920s, the most successful of which was the American film The Student Prince in Old Heidelberg (1927).
