It's always encouraging when a heartthrob turns out to be genuinely blessed with substance and isn't quite as much of a himbo as you thought he'd be. To wit: [ALOUD] presents “Shooting Reflections: Film and Social Change” with actor Diego Luna in conversation with Mandalit del Barco. Luna — who's been everything from a telenovela child star to the smoldering wastrel in Y tu mamá también to a Michael Jackson impersonator in Harmony Korine's Mister Lonely — is directing Chávez, a forthcoming feature on Cesar Chávez that's the logical extension of his 2007 documentary J.C. Chávez. Straight-shootin', slow-talkin' NPR correspondent del Barco will unveil the impassioned and altruistic side of Luna as he speaks about the international arms trade, his life in films and his labor of love, Ambulante, which brings documentary films to remote places in the Americas.
