Aaron Green (Jonah Hill) gets things done. The ambitious 23-year-old has exaggerated his way into a dream job just in time for a career-making assignment. His mission: Fly to London and escort a rock god to L.A.’s Greek Theatre for the first-stop on a $100-million tour. His warning: Turn your back on him at your own peril. British rocker Aldous Snow (Russell Brand) is both a brilliant musician and walking sex. Weary of yes men and piles of money, the former front man is searching for the meaning of life. But that doesn’t mean he can’t have a few orgies while he finds it.
