Although Julian Halevy was given co-credit for the screenplay and Philip Yordan was given co-credit for the story when the film was initially released, according to official WGA records, Halevy was a pseudonym for writer Julian Zimet and Yordan was a front for writer Bernard Gordon. The WGA changed the screenplay credit to read: "Screenplay by Ben Hecht, Julian Zimet and James Edward Grant. Story by Bernard Gordon and Nicholas Ray." The running time for the film listed in the copyright record was 131 minutes. Circus World was presented in Cinerama for roadshow engagements.
