Filmmaker siblings Jay and Mark Duplass have been making movies together since they were kids. Their short film, 'This is John,' made for $3 on a VHS tape, went to the Sundance Film Festival. They've gone on to do HBO's 'Togetherness,' and films like 'The Puffy Chair.' Their new memoir, 'Like Brothers,' is about the rewards and difficulties of being in such a close, collaborative relationship. Also, Maureen Corrigan reviews the book 'Barracoon.'
