We reported back in February that Fox Searchlight has picked up Tom McCarthy's new film with Paul Giamatti and Amy Ryan and now a supporting cast is filling out. Variety is reporting that Jeffrey Tambor (Arrested Development), Melanie Lynskey (Up In the Air) and Bobby Canavale (The Station Agent) have joined the cast of Win Win.

It was previously reported that Paul Giamatti and Amy Ryan would star in the film, with Giamatti portraying an attorney and high school wrestling coach whose depressed life gets turned upside down when he becomes the legal guardian of a client's grandson. It wasn't clear what roles Tambor, Lynskey and Canavale would have on the film.

McCarthy will direct from a script he co-wrote with Joe Tiboni. Shooting was said to begin on March 15 in New York City.
