CHISUM (1970) - Wayne stars as John Chisum, a real-life cattle king determined to protect his empire against a land-grabbing developer (Forrest Tucker). Wayne's no-nonsense persona snugly fits this lively reworking of the events of New Mexico's 1878 Lincoln County War. THE TRAIN ROBBERS (1973) - Three Civil War veterans (Wayne, Rod Taylor and Ben Johnson) team up with a train robber's widow (Ann-Margret) to recover a half-million in gold. But the dead man's ex-partners want the gold, and they'll kill to get it in this rollicking caper from writer/director Burt Kennedy. CAHILL: UNITED STATES MARSHAL (1973) - Lawman J.D. Cahill (Wayne) can stand alone against an army of bad guys. But as a widower father, he's on insecure footing raising two sons. Particularly when he suspects they're involved in a bank robbery and two killings in this suspenseful blend of action and heroic sentiment. McQ (1974) - As Detective Lon McQ, Wayne thunderously enforces the law in a high-velocity thriller that's like a big-city revenge Western on wheels. Directed by action master John Sturges and written by coproducer Lawrence Roman, McQ is a breathless, gritty showcase for the Duke.
