Get Him to the Greek is a very funny movie. There I said it, felt good to get it off my chest.
I just watched it again and laughed out loud for over half the movie. I'm a bit biased though, because I love Russell Brand, Jonah Hill, Elizabeth Moss, and of course Diddy.
Russell Brand was at his finest in his recurring role as Aldous Snow from the classic Forgetting Sarah Marshall.
Aaron and Daphne, played wonderfully by Jonah Hill and Elizabeth Moss, are perfect together throughout. With opposite schedules and opposite ideas, they clash so seamlessly. The threesome build-up and realization has to be one of the most awkwardly funny moments in film history.
Diddy was flat out hysterical. I can't say enough about his "mindf*@#" and "Jeffrey" scenes. I can't quote him in here because it's a family site, but his scenes are absolutely ridiculous.
The soundtrack was created entirely for the film (and of course, Forgetting Sarah Marshall) with a great reference to Kristen Bell's character in the film.
Also, the quick scene with Tom Felton (a.k.a. Draco Malfoy) is classic.
For anyone who hasn't seen it, I HIGHLY recommend it.
