The working title of this film was House of Strangers. Sources conflict concerning the writing credits. The copyright entry states the film was based on the "screenplay 'International Bridge' by Charles S. Belden," and that the adaption of the screenplay was by Belden and Robert Ellis. Hollywood Reporter credits Belden and Ellis with the continuity and dialogue and credits only Belden with the original story, while Motion Picture Herald and Variety credit both with the story. Modern sources list Erich von Stroheim as a technical advisor and a co-scenarist.
