Although he had said long ago that he would make no more biopics, he signed for The Court-Martial of Billy Mitchell. It was a poor Otto Preminger film and even Billy Mitchell's widow expressed disappointment with Cooper's performance. Possibly the story had appealed to Cooper on political grounds and Mitchell may have been a hero of his - the general who accused the government of neglecting military needs. Cooper went on Ed Sullivan's TV show to promote the film and home viewers were quite disappointed - David Shipman referred to Cooper's "effeminate mannerisms in his TV interviews".
Film debut of Elizabeth Montgomery.
Film debut of Jack Lord.
The Mitchell family was very unhappy with the film, especially the casting of the tall, laconic Gary Cooper in the lead role. The real Billy Mitchell was short with an explosive temper. The family thought James Cagney would have been ideal.
