Deadline: Steve Coogan has joined the cast of My Idiot Brother, the Jesse Peretz-directed indie comedy that is shooting in New York with Paul Rudd, Elizabeth Banks, Zooey Deschanel, Emily Mortimer, Rashida Jones and Adam Scott. The film's about family and the sacrifices it takes to deal with them. It's a co-production between Anthony Bregman's Likely Story and Peter Saraf and Marc Turteltaub's Big Beach. Coogan plays a self-righteous documentary filmmaker. Evgenia Petertz and David Schisgall wrote the script.
