Last month we reported that Ed Helms and Jason Segel have joined the new Duplass Brothers film and it seems they have found two new actresses as well. Variety is reporting that Susan Sarandon and Judy Greer have joined the cast of Jeff Who Lives at Home.

The film revolves around two brothers, one who lives with their mom (Sarandon) and the other who suspects his wife (Greer) is cheating on him. They both set out to spy on the wife, which leads to a whole new set of problems. Our earlier story indicated that Greer was potentially up for the role, but now it seems she's signed on. Ed Helms and Jason Segel will play the brothers in the film, with Helms as the married brother and Segel as the title character.

Brothers Mark Duplass and Jay Duplass wrote and will direct the film. No production schedule was announced.
