1. Taylor Lautner
Royally buffing up as the shapeshifting werewolf Jacob Black in the sequel ‘The Twilight Saga: New Moon,’ Taylor Lautner redefines teenage hunk in his breakout role. Graduating from Bella’s long-haired admirer in the first film, Lautner is able to flex his muscles, quite literally, with a much larger, brooding part in the second vampire flick. There is a reason why Taylor beat out the rest of the notable names on this list for the top spot: sheer box office brawn. The Twihards have spoken: Team Jacob all the way — well, for now at least.
Next Up: Reprising his role as Jacob Black in ‘The Twilight Saga: Eclipse.’
