13 Going on 30 (2004)

A 13 year old girl plays a game on her 13th birthday and wakes up the next day as a 30 year old woman.

Slight romantic comedy, quite likable, but utterly predictable as well.

Maltin**1/2: "Variation on (rip-off of?) BIG is plottier than it needs to be but is energized by the irresistable charm of Garner, in her first starring vehicle; Ruffalo is also good as her childhood pal grown up."
