I've never been a Puff Daddy fan. But I have to say, I really liked him in this movie. Well, his character at least.
Spoiler Alert
One scene that made me laugh is when Russel Brands and Jonah Hill were in the plane and see a commercial with Sarah Marshall, Brands says, you know, I think I fucked her before. (Which he did in Forgetting Sarah Marshall).
