Justin Bartha, a.k.a. "the National Treasure comic relief," has just joined Matthew McConaughey, Sarah Jessica Parker and Zooey Deschanel in the Paramount Pictures comedy Failure to Launch.

The film is about a thirtysomething guy (McConaughey) who lives with his parents and uses them as a way to avoid committing to a woman. He changes his mind when he meets the mate of his dreams (Parker). But the slacker has the nagging suspicion that his parents may have hired her in a desperate attempt to get him out of their house. Bartha will be playing a friend of McConaughey's character and will be getting together with Deschanel's character which happens to be a friend of Parker's character. What a wild, wild film!
