From Judd Apatow, the guy that was mostly responsible for 2007 comedies Knocked Up, Superbad, and Walk Hard: The Dewey Cox Story, comes Forgetting Sarah Marshall.

It's the story about a guy who, after his celebrity girlfriend breaks up with him, takes a vacation to Hawaii to clear his mind and try to get over her. Trouble is, he runs into her there, along with her new rocker boyfriend.

The trailer had me laughing out loud.
