Then: Sean Marquette as young Matt
Sean Marquette is an adorable young Matt, and even though we’ll never quite understand how he was supposed to grow up to look like Mark Ruffalo, he’s so sweet that we don’t mind. Matt is Jenna’s geeky best friend, who gifts her a pink dollhouse and magic wishing dust for her 13th birthday. It turns out to be the gift that changes her life, sending her nearly 20 years into the future when the magic dust rains down on her head.

Then: Brittany Curran as one of the Six Chicks
The Six Chicks are the popular girls, the clique that young Jenna will do anything to be a part of. These girls all follow the lead of their queen bee, Tom-Tom. And although these six young women are only in the film for a few short scenes, a number of them, including Brittany Curran, have gone on to have illustrious acting careers. 13 Going on 30 was Brittany’s first Hollywood film, in which she plays an unnamed Six Chick.

Then: Ashley Benson as one of the Six Chicks
Another of the Six Chicks that made it big after 13 Going on Thirty is Ashley Benson. You can see her standing behind Tom-Tom in the opening school hallway scene, and even then, she manages to steal the show when she laughs at Tom-Tom’s joke, flashing a winning smile. It feels like going back in time to see her with that off the shoulder sweater and green scrunchy, and we can’t believe we didn’t spot her sooner!
Now: Ashley Benson
Ashley Benson was a competitive dancer and a singer before she started acting. Although she’s had some television appearances before 13 Going on 30, this was her first time on the big screen.

She also starred in the Bring it On sequel before landing her Pretty Little Liars role as Hanna Marin, for which she is known today.
Then: Mark Ruffalo as Matt Flamhaff
30-year-old Matt Flamhaff is quite possibly the perfect man. Played by Mark Ruffalo, Matt is sweet and sensitive (and, lest we forget, quite handsome) and he helps Jenna out even though she was horrible to him in high school. Matt has a fiancé in Chicago, but after he and Jenna spend some quality time together eating Razzles and dancing to Thriller, they start to fall for each other. Matt grew up to be a very talented photographer and Jenna tries to help him move forward with his career as well.

Other notable credits include Academy Award winning film Spotlight and mystery film Now You See Me.
Then: Brie Larson as one of the Six Chicks
If you look closely, you might be surprised to spot a young Brie Larson in the opening scene of 13 Going on 30, laughing and rolling her eyes at young Jenna in the hallway. Sure, it was a long time ago, and she’s only onscreen for a few minutes, but we think we can spot the future Oscar-winner’s talents even then. It sure is fun to notice so many actresses that we love in this movie from almost 15 years ago.
Now: Brie Larson
Although Brie Larson had several television credits before 13 Going on 30, she rose to fame several years later. The actress, filmmaker, and musician played a number of supporting roles in films such as 21 Jump Street before her breakthrough role in independent film Short Term 12. She went on to win an Academy Award for best actress in 2016 for her starring performance in the drama film Room. What’s next for the talented Larson?

Then: Judy Greer as Lucy Wyman
Lucy is 30-year-old Jenna’s frenemy, and her co-editor at Poise magazine where she works. Played by Judy Greer, Lucy is grown-up mean girl Tom-Tom, who apparently became Jenna’s bestie after that fateful birthday party. Although she’s Jenna’s only friend, she’s not loyal at all, and is constantly trying to outdo Jenna. Although Lucy seems to be helping Jenna out in navigating her grown-up life, Jenna overhears Lucy bad mouthing her, and knows something’s gotta change.
Now: Judy Greer

She has a lot coming out soon, including a leading role in the next movie in the Halloween horror franchise.
Then: Alexandra Kyle as young Tom-Tom
Alexandra Kyle’s Tom-Tom is leader of the Six Chicks, and the meanest of the bunch. Jenna agrees to do Tom-Tom’s homework so that the popular girls will come to her birthday party, and come they do, but only to humiliate poor Jenna. Young Kyle is perfectly brutal in the role of Tom-Tom, who likes to put others down in order to make herself feel good, and grows up to be none other than Jenna’s selfish frenemy Lucy.
Now: Alexandra Kyle
Alexandra Kyle got a young start at the age of eight in the 1996 thriller Eye for an Eye. After her role as Tom-Tom in 13 Going on Thirty, Kyle had several guest appearances in television shows including Without a Trace and soap opera Days of Our Lives, as well as a recurring role in the crime drama series Justified.

Then: Christa B. Allen as young Jenna
12-year-old Jenna, played by a young Christa B. Allen, is gawky and awkward (but let’s face it, who wasn’t at that age?) and just wants to be accepted by the Six Chicks, the most popular girls in school. When everything goes humiliatingly wrong at her 13th birthday party during a game of “seven minutes in heaven,” she locks herself in the closet and wishes to be “30, flirty, and thriving.” Allen is so sweet and genuine in the role and truly looks exactly like a young Jennifer Garner.
Now: Christa B. Allen
Christa B. Allen looks so much like Jennifer Garner, that she played the younger version of her again in Ghosts of Girlfriends Past, five years after 13 Going on 30.

But Allen has had plenty of roles of her own, including co-starring as Charlotte Grayson in the television drama series Revenge. She also guest starred in a number of television series including Medium, medical drama Grey’s Anatomy, and CSI.
Then: Renee Olstead as Becky
Grown-up Jenna runs into another 13-year-old in the elevator – her neighbor Becky, played by Renee Olstead. She starts up a conversation with her, much to Becky’s surprise, because this Jenna usually ignores her, and it’s one of the most memorable scenes of the whole movie. The two complement each other on their clothes and Jenna even invites Becky to come by her apartment sometime. It’s clear that Jenna feels much more comfortable with Becky than with any of the other adults.
Now: Renee Olstead

So Jenna goes on a mission of sorts, to right her wrongs. Garner is absolutely charming as the girl in the body of an adult, and she received applause from a number of critics, while we all fell in love the character.
Now: Jennifer Garner

She will come back to the big screen as an action star in thriller Peppermint, to be released this fall. And we would be remiss without mentioning her magazine-cover marriage to Ben Affleck in 2005, which ended after they separated ten years later and divorced in 2017.
Then: Kathy Baker as Bev Rink
Kathy Baker played Jenna’s wise mother, Bev Rink. At the beginning of the movie, Bev is the caring mom who just wants her nearly-teenage daughter to be happy, and doesn’t understand why she’s struggling so much. 30-year-old Jenna has lost touch with her mother, however, and when she goes back to visit her, Bev gives her some of the best advice of the movie, telling her that she doesn’t regret her mistakes because they helped her “make things right.”
