I'm probably a little overly excited about Jeff Who Lives At Home, the next comedy from directing brothers Mark and Jay Duplass. It's entirely because I saw their upcoming film Cyrus at Sundance and fell in love with it, and with their new movie starring Ed Helms and Jason Segel, it's hard to imagine a better possible team.

Now two more people have joined the movie to thrill me all over again-- Variety reports that Judy Greer will play the wife of Helms's character, who he believes is cheating on here, while Susan Sarandon will play the devoted mother who lets Segel's character, the Jeff of the title, live at home with. The movie's plot sets in motion when the brothers decide to spy on the wife, though if the movie is anything like Cyrus it will be a series of natural-seeming events that result in comedy anyway.

Greer's casting is particularly exciting, since she's a hilarious actress who shines on television-- "Say goodbye to these!" for Arrested Development fans-- but largely gets stuck with the "best friend" role in the movies. Can the Duplass brothers finally give her the kind of role she deserves? I think you know how I feel about the answer to that question.
