Noah Baumbach, best known for his films The Squid and the Whale and Margot at the Wedding, has a new movie in theaters nationwide today. It’s called Greenberg, and it follows a narcissistic man-child played by Ben Stiller as he tries to get his life together.

Baumbach talks with us about why he chose Stiller for the role, whether he sees Greenberg as a ?guy movie,? and what it’s like working with his real-life wife Jennifer Jason Leigh, who appears in the film and shares story credits.
