The 2004 romantic comedy film 13 Going on 30 tells the story of Jenna Rink at 13 years old, played by Christa B. Allen, and at 30 years old, portrayed by Jennifer Garner, and another movie stole this casting idea a few years later. 13 Going on 30 starts on Jenna's 13th birthday in 1987. But when she tries too hard to fit in with the popular group and is embarrassed by her best friend Matty, Jenna accidentally uses "magic wishing dust" to time travel to what is supposed to be the best time of anyone's life — her thirties.
