Man on a Tightrope is a 1953 American film noir directed by Elia Kazan, starring Fredric March and Terry Moore and Gloria Grahame. It was entered into the 3rd Berlin International Film Festival. The screenplay by Robert E. Sherwood was based on a 1952 novel of the same title by Neil Paterson. Paterson based his true story, which first appeared as the magazine novelette International Incident, on the escape of the Circus Brumbach from East Germany in 1950. Members of the Circus Brumbach appeared in the film version in both character roles and as extras.
