After winning millions of hearts worldwide as Dr. Claire Browne in the hit medical drama The Good Doctor, British actress Antonia Thomas is officially preparing to return to the spotlight in an exciting brand-new screen project — and it might be her most surprising role yet.
According to recent production updates, Thomas has been cast in the upcoming mystery drama series Agatha Christie’s Tommy & Tuppence, where she will take on the lead role of the fearless and unpredictable Tuppence.
The new show is described as a contemporary reimagining of legendary crime writer Agatha Christie’s iconic detective duo — bringing the classic characters into a modern-day setting filled with suspense, secrets, and psychological twists.
Best known for her emotional performance throughout four seasons of The Good Doctor, Thomas became one of the most beloved characters on the show before departing in 2021, later returning briefly as a guest star. Since then, fans have eagerly awaited news of her next major on-screen appearance — and this new project could mark a bold shift from hospital hallways to high-stakes investigations.
Even more intriguing, the actress is also attached to the upcoming BBC drama Two Weeks In August, where she will appear alongside a star-studded ensemble cast in what insiders describe as a tense, character-driven story.
With multiple projects now in development and a leading role in a globally recognized literary adaptation, 2026 is shaping up to be a major comeback year for Antonia Thomas — proving that while she may have stepped away from scrubs, she’s far from stepping away from the screen.
Fans of Claire Browne may want to get ready… because Thomas is about to return in a whole new way.
