 John Wayne (I) (qv) strongly disliked this movie because he knew  it was an allegory for blacklisting, which he and his friend  Ward Bond (qv) had actively supported. Twenty years later he was  still criticizing it in his controversial interview with Playboy  magazine in May 1971. Inventing a scene that was never in the movie,  he claimed Cooper had thrown his marshals badge to the ground and  stepped on it. He also stated he would never regret having driven  the blacklisted screenwriter Carl Foreman (qv) out of Hollywood.
