You probably won't spot Elvis in Hawaii, but you might run into your ex! That's what happens to Peter Bretter (Jason Segel) when he flees to Oahu after getting dumped by girlfriend Sarah (Kristen Bell). Surprise—she's vacationing at the same resort with her new rock-star lover (Russell Brand). Writer/star Segel gives this funny rom-com the perfect mix of bawdiness and vulnerability. We're never forgetting his full-frontal nude scene!
