Colt 45 is certainly a lite western for RS but nevertheless is worth a shot. What I found most interesting are how many familiar actors from later big movies make their lesser screen appearances here. Ruth Roman is the only female in the picture and has everybody's attention. She even manages to throw some dirt at and a knockout of RS. Probably the only time this has happened to Scott on screen. She is a few years ahead of Far Country with Jimmy Stewart. Walter Coy, Aaron Edwards in The Searchers, has an uncredited role here that you'd have to Search for. Lloyd Bridges predates his paranoid role in High Noon with a complete weasel of a character here. The catch of the day is Ian McDonald playing Miller here, a member of Zachary Scott's gang; later as Frank Miller in High Noon.
As for the flick, Scott looks clean shaven even after forty days of soft time in jail. Brother Zachary looks like a very light weight Clark Gable. The sexual symbolism is a little too obvious here but for young kids it was all surely missed. Just relieved that RS is clearly interested in Roman with Ruth more than his colts. This is one western where the Indians (unnnamed tribe) are the good guys. It's not The Tall T or Commanche Station but if you are a fan of RS, and I certainly am, you can't miss with a Colt 45.
