What's He Done: Disney darling Zac Efron has been a teen heartthrob ever since his turn as Troy Bolton in "High School Musical," "High School Musical 2" and 'High School Musical 3: Senior Year.' The hunky actor showed off his moves once again in the musical 'Hairspray' (2007) and teen comedy '17 Again.' Wanting to change his image, the 23-year-old recently starred in the drama 'Charlie St. Cloud,' which tells the story of a young man coping with the death of his little brother.
What's Next: Efron is ready to hit the big screen with the ensemble film 'New Year's Eve' and 'The Lucky One' about a marine in North Carolina on the search for an unknown woman he believes was his good luck charm during the war.
