Director and actor Ross Partridge and actor Oona Laurence discuss their new film Lamb. The provocative film—based on Bonnie Nadzam's novel—centers on the unusual friendship between David Lamb (Partridge) and Tommie (Laurence), a neglected 11-year-old girl he's drawn to. When he takes her on a road trip from Chicago to the Rockies, the journey shakes them in ways that neither expects.
