Peter Debruge Chief Film Critic A faux-elegant fable about how not to resolve your differences, made for dudes, by dudes, “The Duel” arrives at a time of intense division (and no small amount of scrutiny over gun use) in America. Releasing as a one-night-only screening via Iconic Events on July 31 before hitting streaming in August, the movie looks sharp enough, but lands like a rapier with a cork on it, as Dylan Sprouse and Callan McAuliffe play longtime besties who try to settle a dispute the old-timey way … by blowing each other away with pistols.
