The title of Paolo Sorrentino's new film is a bit of obvious misdirection. Make no mistake: Youth is about getting hella old, and to its credit, it makes becoming creaky and gray look like it's maybe not the worst thing in the world. It helps that composer Fred Ballinger (Michael Caine) and film director Mick Boyle (Harvey Keitel) have been hugely successful in their work—their moneyed lifestyles permit them an extended visit at the incredibly plush Swiss spa where almost all of Youth is set. by Ned Lannamann
