..."Blood on the Moon" still stands out from run-of-the-range action dramas. The reason is obvious enough. This picture has a sound, sensible story to tell and, besides, it is well acted. Robert Mitchum carries the burden of the film and his acting is superior all the way...Lillie Hayward's screen play, taken from a novel by Luke Short, is solidly constructed and by not over-emphasizing Jim Garry's inherent honesty, she has permitted Mr. Mitchum to illuminate a character that is reasonable and most always interesting. The same can be said of the rancher's daughter, whom Miss Bel Geddes represents. Others who give worthy help include Walter Brennan, Mr. Preston, Phyllis Thaxter, Frank Faylen and Tom Tully. And a word should be said, too, for the direction by Robert Wise. A comparative newcomer to the directorial ranks, he has managed to keep the atmosphere of this leisurely paced film charged with impending violence.
