The Implacable Three (1963) trailer
This early euro-western spins a classic tale of revenge as a rancher and two of his amigos seek the seven stinking gunslingers who ripped off his ranch and killed his wife. Geoffrey Horne (who appeared in "Bridge on the River Kwai") toplines the cast, with great support from spaghetti western icon Fernando Sancho in one of his rare good guy roles.
