The team responsible for The 40 Year Old Virgin and Knocked Up is behind this sometimes riotous anti-romantic comedy. After musician Peter (Jason Segel) is dumped by his TV-star girlfriend Sarah (Kristen Bell), he decides to take a trip to Hawaii to get over her. But when Peter arrives, he discovers that Sarah and her new British rock star boyfriend (Russell Brand) are not only staying at the same resort, but in the very same hotel. All three leads are likeable and well cast, while the Hawaiian scenery looks great. But like producer Judd Apatow's previous films, it is somewhat overlong, with several scenes apparently included because they could be, not because they should be. As compensation, it is often laugh-out-loud funny, with Apatow's broad humour delivering belly laughs by the barrel-load.

When actress Sarah Marshall dumps aspiring musician Peter Bretter for rock star Aldous Snow, Peter's world comes crashing down. His best friend Brian suggests that Peter should get away from everything and to fly off to Hawaii to escape all his problems. After arriving in Hawaii and meeting the beautiful receptionist Rachel Jansen, Peter is shocked to see not only Aldous in Hawaii, but also Sarah.
