This Spanish-Italian production, released internationally under more than a dozen titles, is set in the English countryside, where an experimental machine designed to kill insects has the unintended effect of reviving dead humans. The zombies nearly get Ray Lovelock and Cristina Galbó, and local police sergeant Arthur Kennedy is of no help to the two travelers - he blames them for the rash of homicides.

James Stewart stars as a former border raider who narrowly escapes the hangman's noose (he still smarts from the rope) and is trying to start over again in the wide-open Oregon country. Instead, he winds up involved with the wily and charming Arthur Kennedy in a wagon train that includes the eligible Laurie Baile (Julie Adams) and a load of supplies worth their weight in gold. One of director Anthony Mann's finest films, combining action, character and landscape in a seamless and wildly satisfying package.
