The trailer for Forgetting Sarah Marshall, written by and starring Jason Segel, along with Kristen Bell, is online and in theaters, and it’s a nice tweak of tortured, post-breakup masculinity.

Segel (above right) plays Peter Bretter, a guy who gets dumped by his TV star girlfriend, then finds his Hawaiian vacation of intended psychological escape rudely interrupted when it turns out he’s at the same resort as that of Bell’s Sarah and her new beau, bad boy singer Aldous Snow (Russell Brand). The trailer slyly evokes Caddyshack in nicely gentle fashion (courtesy of Kenny Loggins’ “I’m All Right”) and capably works in its bit players (Paul Rudd, Jonah Hill, Bill Hader), all while not overselling the inevitable rebound relationship with Mila Kunis.

I appreciated, too, the fact that Brand’s work wasn’t (presented as, at least) flaming, over-the-top caricature; Jesus, to think what a younger Ben Stiller would have done with the role. And, downmarket demo-baiting appeal aside, the “pearl necklace” bit at the trailer’s conclusion is nicely underplayed — the bow on top being Segel’s guilty-as-charged shrug.
