ZAC EFRON
AGE 20

BROKE OUT IN... Disney's insanely popular High School Musical franchise, and kept the tunes coming last summer as Link Larkin in Hairspray.

WHY HIM Efron can dance (and sing) circles around his cohorts and has been smart about continually upping the ante with each successive project.

WHAT'S NEXT Natch, the next installment of his career-making franchise, High School Musical: Senior Year, hits in October — only this time, on the big screen. The Big-in-reverse flick, Seventeen Again (he plays the young embodiment of an older, regretful guy going back to high school) lands this year, too.
