Antonia Thomas Cast in Amy Poehler’s New Peacock Series

The archeological site at the center of Peacock’s highly anticipated comedy series Dig just gained a significant new inhabitant. Antonia Thomas, widely known for her soulful portrayal of Dr. Claire Browne on ABC’s The Good Doctor, has officially joined the cast of the upcoming series from the legendary comedy duo of Amy Poehler and Mike Schur.

The project, which marks the first major collaboration between Poehler and Schur since the conclusion of Parks and Recreation in 2015, is an adaptation of Kate Myers’ bestselling 2023 novel, Excavations. With Thomas’s addition, the series further solidifies its status as one of the most star-studded ensembles on the 2026 television slate.

The Role: From Surgery to Preservation

In a shift from the high-pressure operating rooms of St. Bonaventure Hospital, Antonia Thomas will portray Clare, the head preservationist overseeing the dig site’s lab and museum in Greece.

According to character descriptions, Clare is a woman most comfortable in a world of high-society privilege—making her a "fish out of water" amidst the dusty, cargo-clad, and casual environment of a working excavation team. Her character adds a layer of sophisticated friction to the group dynamic, as she attempts to maintain professional standards while surrounded by a team that is at various emotional and professional crossroads.

The role allows Thomas to lean into her comedic timing, a talent fans of her work in the British cult hit Misfits and the Netflix rom-com Lovesick know well.

A High-Stakes Archaeological Conspiracy

Dig is not your typical workplace comedy. The series follows four women working at an archaeological site in Greece, each searching for a fresh start or a way to escape their pasts. However, the mundane reality of digging for pottery shards is shattered when the team uncovers a long-buried secret that has the potential to rewrite human history.

What begins as a character study quickly spirals into a high-stakes international conspiracy. The show aims to blend the "found family" warmth of Parks and Recreation with the existential mystery and sharp plotting of Schur’s The Good Place.

The ‘Parks & Rec’ Dream Team Reunites

The series is a major win for Peacock, reuniting Amy Poehler and Mike Schur, whose partnership gave the world Leslie Knope. Poehler stars in the series and co-wrote the pilot episode alongside Schur and J.J. Philbin (Only Murders in the Building).

Thomas joins an elite group of co-stars:

• Amy Poehler: Taking a lead role in her first scripted series in years.

• Hugh Laurie: Starring as Neville, a British professor and archaeology traditionalist who fancies himself a mentor to the team.

• Geraldine Viswanathan: Playing Dylan, an archaeologist returning to the site after a five-year hiatus to handle "unfinished business."

• Fina Strazza: Portraying Patty, an undergraduate assistant who is in way over her head on her first trip outside the U.S.

Antonia Thomas: A Versatile Career

For Antonia Thomas, Dig represents a return to the "series regular" format after her departure from The Good Doctor in 2021 (though she famously returned for guest spots in later seasons, including the 2024 series finale). Thomas has often spoken about her desire for "versatility and creativity," and moving from a network medical drama to a premium streaming comedy is a testament to that ambition.

"I’ve spent a lot of time in the dramatic space," Thomas noted in a recent industry profile. "Getting to work with minds like Amy and Mike—who basically invented the modern sitcom language—is the kind of challenge you don't say no to."

What’s Next for ‘Dig’?

As of February 2026, Dig is moving into active production on location in Greece and at Universal Studios. While a premiere date has not yet been set, the buzz surrounding the project suggests it will be a cornerstone of Peacock’s late 2026 schedule.

With the combined forces of Amy Poehler’s wit, Mike Schur’s heart, and Antonia Thomas’s effortless charm, Dig is poised to be more than just a comedy—it’s an exploration of the secrets we bury and the friends who help us dig them up.
