MATTHEW PERRY has just signed on to play the older version of ZAC EFRON in the upcoming comedy '17,' according to Reuters. The former "Friend" plays a middle-aged father who magically wakes up to find out he's a teenager again -- which is where 'High School Musical' star Efron picks up the role.

'Knocked Up' funnylady LESLIE MANN will play Perry's wife and director BURR STEERS ('Igby Goes Down') is set to helm the film.
