What we learn from our families is often very private. It’s knowledge we keep inside of us – and that the world doesn’t always get a chance to see. Filmmaker Mark Decena is hoping to open a window onto that kind of family life with his new film, The War Inside, involving his own childhood home movies. The film is a project of the Center for Asian American Media, CAAM, which is hosting its 31st annual festival this year and launching a new national initiative to collect and preserve Asian American home movies. KALW's Ben Trefny spoke with Decena about the value of finally bringing these national memories to light, and Decena's personal contribution to the collection.
