Gun Glory (1957)
An obvious blending of Shane and High Noon. Stewart Granger plays a gunfighter who returns to his home ranch after many years and faces prejudice from yellow-bellied townsfolk and his son before a bunch of evil cattle men arrive to start shit up, prove sometimes you need a gun, and no-one subsequently suggests that the cowman and the farmer should be friends. Granger's surprisingly not too bad in buckskins. Made in Cinemascope, but in truth it's really a quickie oatser with a larger than usual budget.
