Little Big Horn (1949, 86 mins.): A cavalry patrol discovers a horde of Indians ready to ambush Custer's 7th Cavalry. They set out to warn General Custer that he is about to embark on a mission of virtual suicide. Gritty and extremely well-acted character studies set this version apart from the familiar telling of a tragedy from U.S. history.
Rimfire (1951, 64 mins.): The western setting is incidental in this unglamorous, well-written tale of mystery and suspense. The story involves the death by hanging of The Abilene Kid, who is innocent of all charges. After death, "The Kid" returns to kill off all of those who sentenced him to be hanged.
The two films paired up in this collection reside somewhere between the Western and noir genres. Volume One of the Western Film Noir series contains LITTLE BIG HORN (1949) and RIMFIRE (1951).
