No Name on the Bullet (1959)
Audie Murphy (below) stars as John Gant, a hired killer who rides into a town where no one is sure whose name is on his bullet. Several townsfolk all with murky pasts believe it's them he's come for.
An intriguing little thriller, perhaps short on action but still high in suspense as paranoia quickly takes over and the sleepy little western town is suddenly awash with guilt and betrayals.
Former World War II hero Murphy is terrific as is Charles Drake as the town doctor as the two collide head to head as the townsfolk begin accusing each other and keep the viewer guessing as to who Gant's target is.
Anyone who enjoys classic Hollywood westerns could do a lot worse than check this out.
