Warners has also released a special edition of “The Cowboys,” as well as six lesser Wayne titles previously unavailable on DVD. That’s for you completists who want to see him rubbing shoulders with Joan Crawford in Jules Dassin’s nutty World War II romance “Reunion in France” (she’s a designer, he’s an American flyer). A piece in last Sunday’s New York Times implies that all of the Duke’s innumerable flicks were now out there. Not by a long shot. “Circus World,” a 1964 misfire that paired the Wayne with Rita Hayworth, is among a batch of Samuel Bronston productions like “El Cid” that are sitting in DVD limbo. Also unseen are six non-Western B’s that Wayne made for Universal release in the mid-’30s: only a couple of them, “I Cover the War” and “California Straight Ahead,” have even been shown on TV. TCM recently showed a beautiful print of a Wayne I’d never heard of: “Arizona” (1931), an oddball western/football flick that represented his only starring role at Columbia Pictures before studio czar Harry Cohn, who believed Wayne was involved with a starlet Cohn had his eye on, exiled him to supporting roles in B pictures. And then there are the films Wayne made at Fox before going to Columbia: only “The Big Trail” is on DVD, and that’s only available in a full-screen version. The concurrently-shot early widescreen version of this Raoul Walsh epic, which turns up on Fox Movie Channel every now and then, is actually a notably better movie. And that’s the truth, pilgrim.
