Not éveryone in Young Hollywood is lounging poolside with a cocktail and a bottle of Hawaiian Tropic this summer. Many of your favorite TV stars are busily spending their hiatus periods furthering big-screen ambitions. Curious what they're up to? Just don your sunglasses and peruse this sizzling sample of their hot new projects:

The O.C.'s Adam Brody has flown north to Vancouver to shoot In the Land of Women, a movie about a writer who moves in with his wacky grandmother after his girlfriend dumps him. Meanwhile, his girlfriend, Rachel Bilson, will canoodle in Montreal with Scrubs star Zach Braff in a remake of the hit 2001 Italian drama The Last Kiss. And Mischa Barton will hook up with Darth Vader, um, Hayden Christensen in Italy for The Decameron, a period piece that follows a pack of young nobles as they wait out the plague.

Desperate Housewives' Jesse Metcalfe is off to Vancouver for John Tucker Must Die, a comedy about a serial cheater who gets his comeuppance when his three ex-girlfriends band together to exact revenge. DH costar Eva Longoria goes to Toronto and becomes embroiled in a plot to assassinate the president in The Sentinel. (The movie also stars 24's Kiefer Sutherland as — what else? — an agent.)
