Duck, You Sucker
A different sort of Sergio Leone Western, this one takes place during the Mexican Revolution, with more politics than usual. But there's still plenty of action, with Rod Steiger as a cigar-chomping peasant who robs banks to liberate political prisoners, and James Coburn as an Irish terrorist trying to flee from his bitter past. They team up to thwart a sadistic officer and help the cause; redemption for the more subdued Coburn provides added depth.
