Jackson Rathbone in 'The Twilight Saga: Eclipse'Independence Day weekend used to belong to Will Smith. This year it belongs to ... Jackson Rathbone?

The young, Disney-bred hunk may not be a household name, but Rathbone plays key roles in both of this weekend's new wide-release movies: as vampire drill sergeant Jasper Hale in 'The Twilight Saga: Eclipse' and as boomerang-wielding warrior Sokka in 'The Last Airbender.' That means he'll be holding down the two top spots on the box office chart and help sell as much as $250 million worth of movie tickets over the extended holiday weekend.
