Daniel Radcliffe is currently lighting up the silver screen as poet Allen Ginsberg in the film Kill Your Darlings, but on October 30 the star got back in touch with his theatrical side at a performance of A Gentleman's Guide to Love and Murder. Starring Tony winner Jefferson Mays and Bryce Pinkham, the madcap new musical follows Monty Navarro—the gentleman from the title—who learns he's ninth in succession to become the Earl of Highhurst, and goes on a quest to murder the eight people (all played by Mays!) ahead of him in line. After experiencing the unabashedly raucous new show at the Walter Kerr Theatre, Radcliffe hung out backstage with Mays, Pinkham and the rest of the company.
