13 Going on 30 (2004)

This comedy fantasy is about a gawky girl, Jenna, who is picked on by her peers and classmates for being too eager to be liked and popular. Locked in a closet on her 13th birthday (after an embarassing round of the 7 minutes in heaven kissing game), she makes a wish to become thirty, flirty and thriving, and when she gets out of her entrapment, she discovers that she's skipped ahead 17 years to become a sexy and successful advertising agency executive (Garner).
