The film is shot partially in colour (using the UFAcolor process) and partially in black-and-white. The film's
art direction was by
Oscar Friedrich Werndorff. The film was made by the
independent Trafalgar Films at
Elstree Studios. The film was a very expensive production, with Tauber himself receiving £60,000 for appearing, which turned into a costly flop on its release. Caught up in the technical procedures of the colour sequences, Grune asked
Wendy Toye to direct the actors for him. ==Cast==
