Zac Efron '17 Again' photos

High School Musical star Zac Efron plays 17-year-old Mike O'Donnell in New Line Cinema's 17 Again.

As what the title suggests, it's a film about a 37-year-old guy (played by Matthew Perry of Friends) who turned into a 17-year-old youngster. (It's like a reverse of 13 Going on 30.)

17 Again hits theaters this April 17, 2009 (US Release) and also stars Leslie Mann (Knocked Up) and Michelle Trachtenberg (Buffy the Vampire Slayer).
