Outrageously funny spinoff of "Forgetting Sarah Marshall" finds rock star Aldous Snow (Russell Brand) at an all-time career low, his sobriety a distant memory. But he gets one last shot at a comeback thanks to low-level record exec Aaron Green (Jonah Hill, not reprising his previous role) whose effort to get the rocker from London to L.A.'s Greek Theatre for a momentous concert leads to a hilarious drug- and alcohol-fueled odyssey. With Rose Byrne, Sean Combs. R-rated version; 110 min./Unrated version; 114 min. Widescreen; Soundtrack: English.
