You probably recognize her voice before you recognize her face. Or maybe it’s the other way around. If you spent any time watching prestige TV in the late 2000s, Madeleine Martin was the quintessential cynical teenager, the moral anchor in a sea of booze and bad decisions on Californication. But if you’re a fan of surreal animation, she’s the voice of a hero in a land of candy and magic.
Honestly, it’s rare to see a child actor transition into such a bizarrely diverse adult career without the typical Hollywood "crash and burn" narrative. She didn't go the tabloid route. Instead, she went to Broadway, then to a dark Netflix horror series, and eventually became a staple of the Adventure Time multiverse.
The Becca Moody Era: Growing Up on Californication
For seven seasons, Madeleine Martin played Becca Moody. It wasn't an easy role. She was the daughter of David Duchovny’s Hank Moody, a character who was basically a walking mid-life crisis. While Hank was out making every wrong choice possible, Becca was there to provide the deadpan reality check.
She started the show at just twelve years old. By the time it ended, she had grown up in front of millions. What’s wild is how much of her real life bled into the show. Martin has mentioned in interviews that the writers would actually talk to her off-set, and some of her own musical tastes and mannerisms ended up in the script. It made Becca feel less like a "writer’s version" of a teen and more like a real person.
People had opinions, though. You can still find old Reddit threads where fans debate her casting, some finding her monotone delivery annoying while others argued she was the only "real" person in a cast of caricatures. She was the direct opposite of the "bombshell" trope, and that was exactly the point.

Beyond the Live Action: A Voice You Know
If you didn’t watch Showtime, you definitely heard her on Cartoon Network. Madeleine Martin movies and tv shows often crossover into the world of animation in ways people don't expect.
- JoJo’s Circus: Long before the teen angst, she was the voice of JoJo Tickle. If you had a toddler in the early 2000s, you’ve heard her voice singing about circus life more times than you'd like to admit.
- Adventure Time: This is the big one. She voiced Fionna, the gender-swapped version of Finn the Human. What started as a "what-if" fan-fiction episode turned into a massive cult following.
- Fionna and Cake: Fast forward to 2023, and she’s the lead of her own spin-off series. The show took a much more mature, meta-analytical tone, proving that Martin could carry a series on her vocal performance alone.
She also lent her voice to the Ice Age franchise, specifically Ice Age: The Meltdown. It’s a career trajectory that is basically a masterclass in "diversify your portfolio."
The Broadway Powerhouse
Most people forget that Madeleine is a theater kid at heart. She wasn't just some kid who got lucky in a TV audition. By the age of seven, she was already on the national tour of The Sound of Music.
She has a list of Broadway credits that would make most veteran actors jealous:

- A Day in the Death of Joe Egg: She played the title role at age ten. It was so well-received that she became the youngest presenter in the history of the Tony Awards in 2003.
- August: Osage County: She originated the role of Jean Fordham. This wasn't some light-hearted musical; it was a gritty, Pulitzer Prize-winning drama.
- The Pillowman: Working alongside heavyweights like Jeff Goldblum and Billy Crudup.
It’s this stage training that probably explains why she can handle the "heavy" scenes in her TV work. There’s a discipline there that you don’t always get with child stars who only know the inside of a soundstage.
Hemlock Grove and the Horror Pivot
In 2014, she took over the role of Shelley Godfrey in Netflix’s Hemlock Grove. She replaced Nicole Boivin for seasons two and three. If you haven't seen it, it’s a weird, gory, Eli Roth-produced supernatural drama.
Playing Shelley was a massive physical departure. The character is a "reanimated" child—essentially a modern Frankenstein's monster—who is massive and physically deformed. It required Martin to do a lot of heavy lifting with just her eyes and body language, as the character was largely non-verbal and buried under prosthetics. It was a bold move for an actress who could have easily spent her twenties playing "the daughter" in various sitcoms.
Recent Work and What’s Next
Lately, she’s been popping up in some of the best-written shows on television. You might have spotted her in a recurring role during the third season of The Marvelous Mrs. Maisel or as Lucy in an episode of What We Do in the Shadows.

She seems to be gravitating toward projects with a specific, heightened aesthetic. Whether it's the 1950s comedy of Maisel or the gothic absurdity of Shadows, she fits into these worlds because she’s spent her whole life jumping between the stage and the screen.
Interestingly, there is another "Madeline Martin" who is a very famous historical fiction author (writer of The Last Bookshop in London). Don't get them confused! Our Madeleine is currently focusing on voice work and research into theater education, even presenting papers at academic conferences like the Association for Theatre in Higher Education.
How to Follow Her Career Now
If you want to catch up on the best of her work, here is the roadmap:
- For the drama fans: Start with Californication. Watch her grow from a kid to a college student across seven seasons. It’s a wild ride, and she’s the only one who doesn't lose her mind.
- For the animation nerds: Watch the Fionna and Cake series on Max. It’s sophisticated, emotional, and shows off her range.
- For the horror buffs: Check out the later seasons of Hemlock Grove. It’s a bit of a cult classic for a reason.
Keep an eye on the theater world, too. Actors with her background usually find their way back to the New York stage sooner or later. If you're looking for her latest updates, sticking to industry trades like Playbill or Variety is your best bet, as she tends to keep a low profile on social media compared to other stars of her caliber.
The best way to appreciate her talent is to watch Adventure Time and Californication back-to-back. The contrast between the two is the best evidence you'll ever need that she's one of the most versatile actors of her generation.
