Get him to the Greek (2010)

Another good piece by Nicholas Stoller. The movie was certainly well
written not to forget a brilliant acting performance by Russell Brand
and Jonah Hill. Jonah was supposed to bring an out-of-control rock star
to the L.A. Greek theater. Though the job seemed to be a piece of cake
it certainly wasn't. Brand happened to be a drug addict not to mention
the fact that he was a sex machine and that his every body part craved
for orgies. Bringing Brand to the Greek really proved to be a Herculean
task for Jonah. There were a lot of guest appearances in the
movie although some might have gone uncredited. Pink, Lars Ulrich, Christina Aguilera, Pharrell Williams and others were spotted. Sergei, played by P. Diddy was certainly another great
performance as a pissed off boss. There were so many HAHA moments in
the movie and I was laughing out loud. There was this 'Jeffrey' a weed
that would make one insane.It was the God of Weed. It happened to be
the cause of some hilarious moments in the movie. Rose Byrne played
Brand's love interest who leaves her in the beginning following his
downfall albeit Brand decides to take a pit stop in order to bring her
back. The movie takes you on an adventure wherein Jonah ( a big fan of
Aldous(Brand) in the movie ) has to bring Aldous to the Greek theater
although deterred by all the temptations entailed in the way but
eventually has to bring him there so as to fulfill the assignment
allotted by Sergio (his boss) which happens to be dream job for him.
