To cast Paul Rudd at the center of your comedy, as My Idiot Brother casting director Jeanne McCarthy chose to do, is a solid start.  To surround him with the likes of Elizabeth Banks, Zooey Deschanel, Emily Mortimer, Rashida Jones, and Adam Scott approaches brilliance.  As such, you can trust that the remaining roles --- now filled by Hugh Dancy, Kathryn Hahn, Shirley Knight, and Janet Montgomery --- are in good hands.

Described as "a comedy about family and the sacrifices it takes to deal with them", My Idiot Brother is currently shooting in New York City.  Hit the jump for the official press release.

HUGH DANCY, KATHRYN HAHN, SHIRLEY KNIGHT AND JANET MONTGOMERY JOIN THE CAST OF “MY IDIOT BROTHER”

New York, NY – July 21, 2010 – Anthony Bregman of Likely Story and Peter Saraf and Marc Turtletaub of Big Beach announced today that Hugh Dancy (“Confessions of a Shopaholic,” “Adam”), Kathryn Hahn (“Revolutionary Road,” “Step Brothers”), Academy Award-nominated actress Shirley Knight, and Janet Montgomery (“Black Swan”),  have joined the cast of the Jesse Peretz directed, “My Idiot Brother,” a comedy about family and the sacrifices it takes to deal with them.  Currently shooting in New York City the film stars Paul Rudd, Elizabeth Banks, Zooey Deschanel, Emily Mortimer, Rashida Jones and Adam Scott.  Jeanne McCarthy is casting the film. Ned (Rudd) is an idealist. His three sisters (Banks, Deschanel and Mortimer) are ambitious.  Ned crashes at each of their homes, in succession, and brings truth, happiness and a sunny disposition into their lives. In other words, he wreaks havoc.

Adding to this cast of characters, Dancy will portray Christian, a pretentious painter friend of Natalie's  (Deschanel) who tries to help Ned grow as a person by showing him another path; Hahn will play Janet, Ned's (Rudd) ex-girlfriend who, out of spite, is keeping him from reuniting with his beloved dog Willie Nelson; Knight will portray Ilene, Ned’s overbearing and over-nurturing mother, who would be overjoyed if her son moved back home and; Montgomery will portray Arabella, a controversial British aristocrat that Miranda (Banks) is profiling for her magazine, a piece that could provide Miranda with the big break she has looking for.

Per Producer Peter Saraf, “The response to Jesse's vision for the film and the disastrously funny script by Evegenia and David has been amazing, and we could not be more thrilled with the amazing actors that will bring these characters to life.”

Written by Evgenia Peretz and David Schisgall, “My Idiot Brother” is being produced by Bregman, Saraf and Turtletaub for their respective companies. Caroline Jaczko, Stefanie Azpiazu and Aleen Keshishian are executive producers.

Hugh Dancy is represented by Gene Parseghian, UTA and United Agents.  Kathryn Hahn is represented by Lindsay Porter at The Gersh Agency.   Shirley Knight is represented by Philip Adelman at The Gage Group. Janet Montgomery is represented by Innovative Artists and Industry Entertainment.
