High School Musical

What Twilight is to Rob Pattinson, High School Musical was to Zac Efron. Then 19-year-old Zac burst onto the scene as Troy Bolton, the MVP of East Side High's b-ball team and, well, the soon-to-be MVP of young Hollywood. Even though he didn't get to sing in the flick (those privileges would come later, as we learned...), he did totally rock that jumpshot -- and those biceps.
