We’ve got a couple of casting stories for you this afternoon. First up, Val Kilmer, Radha Mitchell (Silent Hill) and Kate Maberly (Finding Neverland) have joined the cast of D.J. Caruso’s indie The Goats. Based on the young adult novel by Brock Cole, the story centers on two kids who are stranded on Goat Island following a summer camp prank. Rather than return to camp, the duo set out on their own adventure and run away. Chandler Canterbury (Knowing) and Annalise Basso (Bedtime Stories) are set as the two young leads. Variety reports that Kilmer and Mitchell will play parents, with Maberly taking on the role of a camp counselor. Production on Caruso’s passion project began today in Georgia. Hit the jump for the casting news of Toby Kebbel in Zal Batmanglij’s The East, and a synopsis of The Goats.Additionally, Toby Kebbel (RocknRolla) has joined the already impressive cast of Zal Batmanglij’s The East. Co-written by Brit Marling (who also stars), the film centers on an undercover agent (Marling) whose job is to protect corporations from eco-terrorists and anti-business extremists. When she is sent to investigate an anarchist organization, she finds herself falling for the leader (Alexander Skarsgard). Twitch reports that Kebbel will be playing a character known as Doc. Ellen Page also stars in the drama. This marks the second collaboration between Batmanglij and Marling, who previously teamed up for The Sound of My Voice, which Fox Searchlight is set to release sometime next year.Here's the synopsis for The Goats:

A boy and a girl are stripped and marooned on a small island for the night. They are the “goats.” The kids at camp think it’s a great joke, just a harmless old tradition. But the goats don’t see it that way. Instead of trying to get back to camp, they decide to call home. But no one can come and get them. So they’re on their own, wandering through a small town trying to find clothing, food, and shelter, all while avoiding suspicious adults–especially the police. The boy and the girl find they rather like life on their own. If their parents ever do show up to rescue them, the boy and the girl might be long gone. . . [Amazon]
