In the grand tradition of Tom Hanks, Judge Reinhold, and Jennifer Garner, Matthew Perry is now aging in reverse onscreen in the comedy 17 AGAIN, only this time, his teenage counterpart is HIGH SCHOOL MUSICAL 3 teen dreamboat Zac Efron, so it’s a safe bet the tweens will be flocking to this film like moths to a barechested flame. In it, Perry is granted the opportunity to be 17 again as Efron and with Thomas Lennon helping him, he goes back to high school, tries to connect with his children and is seemingly seduced by his ex-wife, in the form of Leslie Mann. The reverse again magic happens April 17th next year. Check out the trailer below and get it in HD over at Moviefone.
