Judd Apatow, the man behind critically-acclaimed comedies such as “The 40-Year Old Virgin”, “Knocked Up”, “Superbad”, and “Pineapple Express”, produces a spin-off to this year’s “Forgetting Sarah Marshall”. The new movie, entitled “Get Him to the Greek”, will star Jonah Hill and Russell Brand in this buddy comedy where a fresh-out-of-college insurance adjuster (Hill) is hired to accompany out-of-control British rock star Aldous Snow (Brand) to a concert at L.A.'s Greek Theater. And since the direction is on the music scene, Christina Aguilera, Pink, and Katy Perry will grace the silver screen to play themselves. Let’s see how these pop stars will fare as comediennes.
