13 Going on 30: Parents Guide, Plot, Cast & Trivia (2025)

Released in 2004, the film stars Jennifer Garner as Jenna Rink, a girl who wakes up at 30 after a birthday wish, only to find that being grown-up isn’t all it’s cracked up to be.

Release Year: 2004 · MPAA Rating: PG-13 · Runtime: 98 minutes · Box Office (Worldwide): $60.5 million · Rotten Tomatoes Score: 64% · Main Cast: Jennifer Garner, Mark Ruffalo, Judy Greer

Eight key facts, one pattern: the film’s lasting appeal comes from its balance of nostalgia and relatability.

What was the original title?

• Original title in some international markets: Suddenly 30 (Wikipedia)

Why was the name changed?

• Changed to 13 Going on 30 to emphasize the age gap and avoid confusion with the 1990s TV series Suddenly Susan (Mental Floss)

The pattern: the title shift was a smart branding move that made the film instantly recognizable.

What is the wish?
