At the start of World War II, P. G. Wodehouse, then one of the most popular authors in the world, was captured by the Nazis while living in France. After his release, he was duped into broadcasting accounts of his imprisonment to Americans—characteristically light, amusing reports. Bad move. Some in his native England saw him as a traitor, though at worst he was genuinely, if stupendously, naïve—“criminally foolish,” in his own assessment. Wodehouse in Exile, a movie starring the late Tim Pigott-Smith and Zoë Wanamaker that first aired in 2013 on the BBC, deftly dramatizes the one sorry episode in this talented humorist’s life. —George Kalogerakis
