Ben Stiller to Replace Mark Ruffalo on 'Greenburg'
Comedian will take on dramatic role
Ruffalo had been expected to lead the comedy-drama, according to the Hollywood Reporter. Presumably his brother Scott's death during a game of Russian roulette had a role in the decision. While no plot synopsis has been released yet, writer-director Noah Baumbach is known for exploring relationships in films like "The Squid and the Whale" and "The Life Aquatic with Steve Zissou."
