Robert Mitchum comes into the film a little late while he's straight and true as the scripture-spouting preacher who sweeps out the long abandoned church and begins hold services, you know he's hiding something. Yaphet Kotto is fine as the bartender, and Inger Stevens has a small, shining role as the local purveyor of tonsorial delights (a barber). He's a mean, cowardly, lying weasel, and no one ever played a weasel better. While Dean is great, Roddy McDowall is fantastic as the sniveling brother of Dean's girlfriend. Dean spends the rest of the movie trying to figure out who's doing the killing.
One man is strangled with barbed wire, another is drowned in a flour barrel, etc. Soon after the lynching, every one in the game is methodically murdered in the most inventive ways. When he tries to stop the lynching of a cheating player, he's overpowered. Dean Martin is cool and steady as the gambler who takes part in a game of five card stud that turns deadly. Murder mystery westerns don't come along every day, and while this one is kind of slow moving, it's still a great movie.
