You know that feeling when you're scrolling through Netflix or BritBox and you see a face that just makes you go, "Oh, I love her"? That’s the Antonia Thomas effect. Honestly, if she's on the cast list, the show is usually worth the bandwidth. Whether she's playing a surgical resident with a heart of gold or a girl who can literally make people lose their minds with a single touch, she brings this weirdly specific grounded energy to everything.
People always talk about the "big" stars, but Antonia Thomas movies and tv shows are where the real quality is hidden. She’s had this slow-burn, high-impact career that’s basically a masterclass in versatility. You’ve probably seen her in The Good Doctor, but did you know she voiced a Tele-tubby? Yeah, really.
The Roles That Changed Everything
Most people first got hooked on her back in 2009. Misfits. It was this gritty, foul-mouthed British show about young offenders who get superpowers after a weird storm. Antonia played Alisha Daniels. Her "power" was actually kind of a nightmare—anyone who touched her skin became uncontrollably attracted to her. It was a role that could have been super one-dimensional, but she made Alisha feel vulnerable and, frankly, exhausted by the whole thing. It’s one of those performances that still holds up if you go back and rewatch it on Hulu or Channel 4.
Then she took a massive swing and headed to the US for The Good Doctor.
Playing Dr. Claire Browne wasn't just about learning medical jargon. She had to be the emotional anchor for Shaun Murphy (Freddie Highmore). Claire was the one person who really "got" him from the start. It's funny because when she left the show after Season 4, you could feel the vacuum she left behind. Fans were gutted. She’s popped back in for guest spots since then, including a big return in the final season in 2024, but those first four years were peak TV drama.

Why Lovesick is Actually Her Best Work
Okay, hot take: Lovesick (originally called Scrotal Recall, which was a terrible name, let’s be real) is actually her best show. She plays Evie. It’s a comedy about a guy who has to contact all his exes because he has an STI, but it’s secretly one of the most romantic, painful, and funny shows ever made.
The "will-they-won't-they" between her character and Dylan (Johnny Flynn) is agonizing.
But in a good way.
What’s She Doing Lately? (2025 and 2026)
If you’re looking for the newest Antonia Thomas movies and tv shows, things are getting pretty interesting. She hasn't just stuck to the usual hospital dramas.
- Agatha Christie’s Tommy & Tuppence (2026): This is the big one. BritBox just dropped first-look images of her as Tuppence Beresford, starring alongside Josh Dylan and the legendary Imelda Staunton. It's a modern reimagining of the classic detective duo. Thomas playing a "force of nature" actress-turned-sleuth feels like perfect casting.
- Bagman (2024): She recently stepped into the horror/thriller genre in this film. It’s about a family being hunted by a mythical creature. It’s a far cry from the sterile halls of San Jose St. Bonaventure Hospital, but it shows she’s not afraid to get a bit messy.
- Still Up (Apple TV+): This one was a bit of a hidden gem. She played Lisa, an insomniac who spends all night on the phone with her best friend (played by Craig Roberts). Even though Apple unfortunately axed it after one season, it’s still worth a watch for the chemistry alone.
A Career of Quiet Dominance
Antonia Thomas doesn't just do "big" roles. She’s been in the Steve McQueen Small Axe anthology (specifically the "Red, White and Blue" episode). She did the voice-over work for the Teletubbies reboot. She was in a Coldplay music video for "Charlie Brown."

She’s everywhere.
The thing is, she’s a Bristol Old Vic Theatre School grad. That’s top-tier training. You can see it in how she handles dialogue; she never feels like she's "acting." She just exists in the space. Whether it’s a tiny indie film like Sunshine on Leith (which is a musical, by the way—she can sing!) or a massive American network show, she maintains this specific, relatable British charm.
Breaking Down the Filmography
If you’re planning a binge-watch, here’s a loose guide on where to start depending on your mood:
- Feeling nostalgic? Go for Misfits. It’s chaotic and very "2010s Britain."
- Need a good cry? The Good Doctor is the obvious choice.
- Want a comfort watch? Lovesick on Netflix. It’s short, punchy, and incredibly sweet.
- In the mood for a mystery? Keep an eye out for the Tommy & Tuppence premiere on BritBox later this year.
Why We’re Still Watching
The industry is weird. Actors come and go, but Thomas has stayed relevant by being consistently great and picking projects that feel different. She’s not just a "TV actress" or a "film star"—she’s a storyteller.

Honestly, her move into producing (like with the short film Anacoreta) shows she’s looking to have more control over the types of stories being told. We need more of that. Especially from someone who has navigated both the UK indie scene and the US studio system so successfully.
If you haven't seen her in Suspect yet, go find it. It's a noir crime drama where each episode is basically a two-person play. She plays Maia, and the intensity she brings to a single room is wild. It’s a reminder that she doesn't need a big budget or special effects to hold your attention.
To get the most out of her work right now, start with Lovesick for the vibes, then move to The Good Doctor for the drama, and make sure your BritBox subscription is ready for the Agatha Christie drop in 2026. You won't regret it.
