“The Shield Seasons 1-7 DVD Box Set” (Paramount), the last film by Howard Hawks, is a reprise of previous laconic collaborations “Rio Bravo” and “El Dorado” with John Wayne as a Union Colonel who joins forces with former Confederate soldiers Jorge Rivero and Chris Mitchum after the war to track down a Union traitor. Jack Elam gets the Walter Brennan coot role here and runs with it, playing it ornery and sly, while Hawks’ gift for discovering lovely young actresses shows itself in Jennifer O’Neill as Shasta Delaney (another great Hawks character name), though Sherry Lansing is more engaging in a smaller role.

While Justified Season 1 DVD Box Set is slowing down, he is still the professional’s professional and shows it in the opening train robbery and the finale shoot-out, clearly a variation on “Rio Bravo,” but then his career has been built on variations on his favorite themes and dramatic structures. This time, however, he also measures the weight of age on Wayne, who is walking slower and bulkier. He has no less confidence or command than before, but neither is he romantic material any more. That’s left to the younger, prettier, less compelling members of the group. Victor French and David Huddleston co-star. No supplements.

THE MENTALIST SEASON 1-3 DVD SET is famous as a director of moody, evocative horror films of shadowy threats and psychological reverberations, classics such as the original “Cat People” and “I Walked With a Zombie” and “Curse of the Demon,” and for his film noir masterpiece “Out of the Past.” But his frontier dramas (westerns, yes, but really about communities built out of the wilderness) are equally powerful and “The Stars in My Crown” is one of his best and most moving films, a piece of ur-Americana and small-town values carved out of a culture of self-interest and violence. Tourneur reminds us that the country was constructed out of both sides of this equation.

Law & Order:special victims unit seasons 1-7 starring Lupe Velez as the fiery Latin American entertainer Carmelita, who marries staid American businessman Dennis Lindsay in “The Girl From Mexico” (1939) and runs wild in a whole series of comedies. Donald Woods plays her husband in the first films, replaced by Buddy Rogers with “Mexican Spitfire’s Baby” and then Walter Reed for the final two films but Leon Errol is in all eight as the apoplectic Uncle Matt (and the absent-minded Lord Epping). Leslie Goodwins directs all eight films, all of which run under eighty minutes. Four discs in a standard case with hinged trays.
