FILM 2283: 13 GOING ON 30 (2004)

TRIVIA: Jennifer Garner was very happy with the studio's choice of Christa B. Allen to play the young Jenna. She felt Allen really embodied her at that age, and later got the producers of Ghosts of Girlfriends Past (2009) to cast Allen in a similar role.

Mark Ruffalo's first scene was the Michael Jackson: Thriller (1983) sequence. He was terrified of doing it, but Jennifer Garner's enthusiasm was "very infectious". Andy Serkishad to rehearse the scene separately from everybody else, because he was in London at the time.

Jennifer Garner, Mark Ruffalo, and Judy Greer were the studio's first choices to play Jenna, Matt, and Lucy.

The Poise article that Jenna is reading at 13 years old ("Thirty, Flirty & Thriving") features the apartment in which she later lives in when she's 30 years old.

Jennifer Garner spent time with teenagers to remember how to act like one.

Jennifer Lopez is featured on both the Sparkle and Poise magazine covers. Ironically, during the filming of this film, Jennifer Lopez was in a serious relationship with Ben Affleck, Jennifer Garner's future husband.

Brie Larson is one of "The Six Chicks" in the scenes at school and Jenna's party. She also has a line in the first scene. Later in the film, a yearbook photo shows that she is no longer a part of the group, replaced by Jennifer Garner's character as a teen.

Many of the Michael Jackson: Thriller (1983) dancers were choreographer Marguerite Pomerhn Derricks' own dancers, and one of them was producer Gina Matthews.
