When this movie was shown on CBS' Thursday Night At The Movies in 1965, the reels were shown out of sequence. Nobody at the network noticed at first but at approximately 10:30 p.m. the movie suddenly stopped and an announcer's voice was heard apologizing for the mix up. CBS then showed the entire movie from the beginning and it finally ended at about 1 a.m.
