I’m reading Michael Callahan‘s Vanity Fair profile of illustrator Robert McGinnis, “The Man Behind History’s Most Iconic Movie Posters, From Breakfast at Tiffany’s to James Bond.” I know the realm — all those ’50s and ’60s-era illustrations of glammy, cartoonishly rail-thin women, often posed with leading men in tuxedos and suede pumps. But the illustration that got me was “Ethan,” which McGinnis painted 37 years ago. McGinnis’s subjects, curiously, are always slimmer and taller. That’s his trademark unreality. The Duke, 48 and bulky when he made The Searchers, is down to his Big Trail weight.
