The Gunfighter (1950) is a Western that resembles a theatrical drama in that its action is there but minimal.
Gregory Peck plays a no-longer-mean shooting ace pursued by the brothers of a man he killed in self-defense. Henry King directed the film tidily and knowingly, and had a good editor in Barbara McLean. Peck never stumbles as a troubled man, though Millard Mitchell is too stiff as a tough marshal. Karl Malden proves his reliability in an early role.
This is King’s baby, but even more it is the baby of one William Bowers, who co-invented the story and co-authored the script.
