JONAH HILL
AGE 24

BROKE OUT IN... Judd Apatow's teen-sex romp Superbad as desperate-for-booze-and-sex high school senior Seth.

WHY HIM There's something undeniably loveable about his plump appearance and general well-intentioned demeanor in the broad comedies he's made. Plus, barring any huge Apatow-backlash, he'll be busy with roles alongside that comedy troupe for a long time to come.

WHAT'S NEXT Besides voicework alongside Seth Rogen in Horton Hears a Who, Hill gets back in step with Knocked Up co-star Jason Segel in Forgetting Sarah Marshall (April 18).
