A couple of American mercenaries head to Mexico hoping to profit from the revolutionary war there. Cooper and Lancaster play characters that are complete opposites: one is quiet and long in the tooth and the other is brash-talking and flashes a toothy grin. It is not hard to guess which actor plays which role. Lancaster, dressed in all black, hams it up while Cooper is subdued. The film is generally entertaining but the script is too routine to raise it above mediocrity. Romero is smooth as a Mexican army official. Darcel and Moniel provide the love interest while the supporting cast features the likes of Elam, Borgnine, Bronson.
