Samuel Fuller's screenplay took liberties with the established style of the show by eliminating a primary series protagonist early in the episode in order to introduce a one-time American character to helm the investigation, by conducting the majority of the program in English rather than German (though subtitles were provided in the German broadcast), and by ultimately treating the story with a satirical and often broadly comic tone.
Samuel Fuller was offered the opportunity to direct an episode of the popular German crime drama by film critic (and later writer/director) Hans-Christoph Blumenberg, in appreciation for the director's help in securing interviews with filmmakers Howard Hawks and John Ford for a documentary project. Upon meeting with the program's producers and feeling initial doubts about being able to conform to the show's standard template, he suggested a storyline inspired by the then-recent Profumo affair in England, which the producers approved to Fuller's surprise.
On the desk of the Manager of the London Bridgeport Hotel is a book whose title is "144 Piccadilly". The author was Sam Fuller.
This Samuel Fuller movie has an English language soundtrack and because of the director and its festival exposure as a theatrical film it is better known under the English title, while previous exposure as a TV segment was ephemeral.
