I just saw this on TCM.?I am a huge Gary Cooper.( Captain. Jack Gaillard) fan and he is the primary reason to watch Operator 13. I am quite aware that his is a Cosmopolitan Picture and that means. Marion Davies ( Gale. Loveless) and her lover William Randolph Hearst made sure that she dominated her movies, but not here ( I wonder if that is why Davies left MGM after this film?). One other thing I liked were about he action scenes. Watch a scene where Confederate soldiers.are getting killed in a river trying to escape. I wonder if Sam Peckinpah saw this movie because it reminded me of Major Dundee with Charlton Heston and Richard Harris ( except there it was Mexicans doing the killing instead of Union soldiers). I will warn this movie is not for the sensitive ( PC types) because Davies is in blackface with an obvious mistake of her hands being white. I give this movie 9/10 primarily for Cooper and the war scenes.
