Have you wondered what the 13 Going On 30 cast has been doing? Because I certainly have, literally twenty years later.

I have a lot of comfort movies in my life, and one of them has always been 13 Going On 30. If we’re talking about a movie that still holds up, 13 Going On 30 is one of those. Not only are the performances great, but the story always makes me want to watch it over and over. It’s crazy to think that the young Jenna Rink is now over 30 - amazing how seventeen years go by just like that. However, since so much time has passed since this film originally came out, one might wonder where the cast is now - and what they might be doing next – and this list is your answer!

Jennifer Garner (Jenna Rink)

Jennifer Garner is the lead in 13 Going On 30, and has done plenty in Hollywood since the romantic comedy. Some of her biggest roles have been starring in several romantic comedies, such as Ghosts of Girlfriends Past or Valentine’s Day. She’s also starred in movies like Yes Day, Love, Simon, Dallas Buyers Club, and more.

Another big role that she had while filming 13 Going On 30, and resumed after the film’s release, was starring in and being a part of the Alias cast - which is even cooler because the cast reunited in 2021. Garner appeared in several other films over the last few years, including The Adam Project, Deadpool & Wolverine, and Family Switch.

Coming up, she’ll be in a new film called Mrs. Claus for Netflix, and appeared in a new true-crime film called Fruitcake alongside Paul Walter Hauser.

Playing the young Jenna Rink in 13 Going On 30 was Christa B. Allen, and she’s appearing in both movies and TV shows since her big role in the romantic comedy. Some of her biggest appearances were a reunion with Jennifer Garner in Ghosts of Girlfriends Past, Detention of the Dead, The Valley, and other movies.

She’s also had quite the career in TV as well. Allen had a main role as Charlotte Clarke in Revenge, as well as a recurring role in the series, Baby Daddy, and most recently, she appeared in the film Meet Me In Rome in 2024.

Mark Ruffalo (Matt Flamhaff) 

I feel like everyone knows who Mark Ruffalo is now thanks to his amazing performance as the Hulk in Marvel Cinematic Universe, as well as his many other roles, but before the Hulk, he portrayed Matt Flamhaff in 13 Going On 30. Aside from the Hulk/Bruce Banner in the MCU, some of his biggest roles have been in Shutter Island, The Kids Are Alright, and many critically acclaimed movies like Foxcatcher,Spotlight, and 2023’s Poor Things, which earned him an Academy Award nomination.

Ruffalo has also had success in television, appearing in the TV film, The Normal Heart and the miniseries, I Know This Much Is True, as well as the miniseries All The Light We Cannot See. Coming up, Ruffalo will appear in Now You See Me 3, the highly-anticipated Mickey 17, and more, so keep an eye out for him (as always).

Sean Marquette portrayed the younger version of Matt Flamhaff in 13 Going On 30, and he’s also been successful since.

Besides that, he’s also had a major recurring appearance on The Goldbergs as Johnny Atkins, a role he played again in the spin-off, Schooled.

Marquette has also appeared in a variety of movies, like Grilled, High School, Friend Request and more.

Judy Greer (Lucy “Tom-Tom” Wyman) 

I feel like all of us have a Lucy “Tom-Tom” Wyman somewhere in our lives, but the original was played by Judy Greer in 13 Going On 30. Greer has established herself as a force to be reckoned with due to her many movie and TV appearances.

Some of her biggest movie roles have been the romantic comedies 27 Dresses and Love and Other Drugs, the horror remake, Carrie, Dawn of the Planet of the Apes, 2018’s Halloween and its two sequels, the Ant-Man films in the MCU as well as Guardians of the Galaxy Vol. 3, Aporia and so many more.

Greer has also appeared in many television shows (truly too many to list). Some of her most recognizable have been The Big Bang Theory, Arrested Development, Two and a Half Men, Married, and Kidding alongside Jim Carrey. She even held a role in the miniseries The White House Plumbers in 2023.

Coming up, Greer will appear in several movies, including The Fire Inside, The Best Christmas Pageant Ever, The Fisherwoman, and more.

Next up, we have Alexandra Kyle, who played the younger version of Lucy “Tom-Tom” Wyman in 13 Going On 30. Like her other younger co-stars, Kyle has had success in both movies and TV, appearing in films like Funky Monkey, and having recurring roles in shows like Justified and Days of Our Lives.

Kyle doesn’t have anything new coming up soon, but it does seem like she’s breaking into the world of directing and writing. She produced, directed, wrote, and starred in her own short, Anxiety Wilma in 2022, and since then she’s made a few other shorts as well, so keep an eye out for her.

Andy Serkis (Richard Kneeland) 

You know, I’ll admit, when I first saw Andy Serkis in 13 Going On 30, I almost didn’t recognize him because I’m so used to his brilliant motion-capture performances where you don't see his face. This movie just proved that Serkis, as Richard Kneeland, was the perfect casting decision, as I can't picture anyone else but him playing the role.

Serkis, as you probably know, has gone on to do so much in Hollywood. Some of his biggest roles have been portraying Caesar in The Planet of the Apes revival, a major role in the Adventures of Tin-Tin series, motion-capturing Supreme Leader Snoke in the Star Wars sequels, as well as many other movie roles. He also had a leading part in the TV miniseries, The Letter for the King, playing Mayor Mistrinaut. He even appeared in The Batman cast in 2022, and had a pretty big guest role in Andor.

Now, he’s producing The Bastard Son & the Devil Himself, as well as the new TV series, Brilliant Minds.

Baker has been active in both movies and TV since her work here. Some of her biggest movie appearances have been Saving Mr. Banks, Nine Live, Big Miracle, The Art of Racing in the Rain, and many more.

She’s also had success in TV. Baker has had recurring roles in many shows including, Medium, Against the Wall, Those Who Kill, I’m Sorry, and more. Baker also had a leading role in the Netflix series, The Ranch during its run, where she played Joanne. Now, she’s appeared in a new show called Teacup on Peacock in 2024.

Some roles you might recognize him from are playing Father in Blades of Glory, one of the committee members in Evan Almighty, Don Parker in A Thousand Words, Principle Kent in the Dwayne Johnson/Kevin Hart buddy cop movie, Central Intelligence, and many others.

He’s also had quite the career in television, appearing in many shows. Some of his biggest roles were playing Andrew Doyle on Veep, Charles Swedelson on Girlfriends, Gene in The Detour, and more. While he doesn’t have anything coming up soon, he was a part of the series, Home Economics in 2021, and had a guest role on the show American Auto.

Susan Egan (Tracy Hansen) 

Last, but not least, we have Susan Egan, who played Tracy Hansen in 13 Going On 30, one of Jenna’s co-workers when she was thirty. Since her role in the film, Egan has appeared in many movies and TV shows, like The Third Wish movie, Modern Family, and others, but her biggest role thus far was voicing Rose (as well as other minor characters) in the popular TV series, Steven Universe.

Egan is also known for her talented voice-acting, and has guest-starred on shows such as The Simpsons, Amphibia, and has voiced many characters in video games like Spider-Man 2, and the Kingdom Hearts series. She’s continued several voice roles since then, working on shows and games like Disney’s Speedstorm, Bjorn the Last Unicorn and more.

After such an iconic film, it only makes sense that these famous actors and actresses have gone on to do so much in the industry, and I for once can’t wait to see what they do next.
