The Boys of ’36 (9/8c, PBS, check local listings at pbs.org): Who doesn’t love a good underdog story, especially at Olympics time? It’s hard to imagine a more satisfying come-from-behind triumph than the one told in a new American Experience documentary, well timed to air just a few days before the Rio Games get underway. Listing among its producers NBC Olympics correspondent Mary Carillo, this will be familiar to those who’ve read The Boys in the Boat: Nine Americans and Their Epic Quest for Gold at the 1936 Berlin Olympics. That best-seller’s author, Daniel James Brown, is among those interviewed in an inspiring if glancing 80^th-anniversary history of the Depression-era rowing crew from the University of Washington. Composed of working-class men from modest backgrounds, the team upstaged Ivy League rivals on its way to earning gold at an Olympics dominated by Nazi hosts. Newsreel footage of their victory is thrilling, making you hope a long-in-development movie version someday comes to pass. These heroes deserve it.
