Since Doc Martin wrapped, Catz has not slowed down. She can currently be seen in A Small Light on Disney+, playing Auguste van Pels (Independent Talent Group (official talent agency)). She also directed, wrote, and produced the documentary Delia Derbyshire: The Myths & The Legendary Tapes, which won the Adam Yauch Special Jury Prize at SXSW (Independent Talent Group (official talent agency)).

Post-Doc Martin projects

Beyond the Disney+ series, Catz has taken on character roles in A Very British Scandal (2023) and the short film The Extraordinary Miss Flower (2024) (Wikipedia (community-edited biography)). She also narrated the 2025 documentary Inside China: The Battle for Tibet (Plex (streaming database)).

Directing and writing work

Catz’s filmmaking debut earned critical acclaim. Delia Derbyshire: The Myths & The Legendary Tapes documents the life of the pioneering electronic musician and won multiple international awards (Independent Talent Group (official talent agency)).

Audiobook narration

Catz remains active as a narrator for audiobooks, though specific titles are not widely listed in public filmographies.

The variety of her current work shows a deliberate move beyond her Doc Martin persona.

What happened to Louisa on Doc Martin?

Louisa Glasson, the headteacher who captured the heart of the grumpy GP, remained in the fictional Cornwall village of Portwenn through the final series. Her arc includes marriage to Martin Clunes’s character in season 5 and the birth of their son James in season 6 (Wikipedia (community-edited biography)). By the end, Louisa and Martin are still together, running the local school and surgery respectively.

Louisa’s storyline in the final series

• She continues as headteacher at Portwenn Primary School.
• The couple faces the usual small-town mishaps but remains united.
• No dramatic exits or deaths — the show ended on a hopeful note.

Her marriage to Doc Martin

The wedding, a long-will-they-won’t-they payoff, finally happened in the 2011 Christmas special (season 5). Their relationship is one of the most enduring in British TV drama, spanning 18 years on screen.

Her role as a teacher

Louisa’s teaching career was a central part of her identity, often providing a foil to Martin’s clinical brusqueness. She balanced motherhood and work, a narrative thread that resonated with many viewers.

This peaceful resolution reflects the show’s enduring appeal.

Her privacy is a conscious decision that shapes her public persona.

Are Martin Clunes and Caroline Quentin still friends?

This question often confuses Caroline Catz with Caroline Quentin, another British actress. Martin Clunes and Caroline Quentin are friends from their time on Doc Martin? Actually, Quentin was never on Doc Martin. The friendship between Clunes and Quentin dates back to Men Behaving Badly in the 1990s. Catz and Clunes, however, have maintained a professional friendship since the show ended. In a 2022 UPI interview, Catz said she and Clunes are “still very close” and that working together was “a joy” (UPI (news wire service)).

Caroline Quentin and Martin Clunes co-starred in the comedy Men Behaving Badly and have remained friends. They have appeared together at charity events and stage shows.

Co-stars on Doc Martin and other shows

Clunes and Catz shared 18 years on set. Catz described the atmosphere as “like a family” and noted that the cast stayed close throughout the run (PBS SoCal (public broadcaster affiliate)).

Public appearances together

Since the show ended, Catz and Clunes have not made many joint public appearances, but Catz attended the premiere of Clunes’s documentary about dogs in 2023.

The confusion itself highlights how closely Catz is associated with the show.

In her own words and from co-stars

“I don’t think anyone ever gets tired of the show. It’s such a lovely, warm hug of a programme.”

— Caroline Catz, UPI interview, November 2022 (UPI (news wire service))

“There was a moment when I was walking along the coastal path near Port Isaac and I nearly went over the edge. It’s very beautiful but dangerous.”

— Caroline Catz, PBS SoCal interview (PBS SoCal (public broadcaster affiliate))

“Working with Caroline was always a pleasure. She brought a natural warmth to Louisa that made the whole show work.”

— Martin Clunes, as quoted in Express coverage (Express (UK lifestyle publication))

Caroline Catz has quietly built a post-Doc Martin life that balances creative ambition with personal privacy. For fans who miss Louisa Glasson, the comfort is that Catz is still making meaningful work — just on her own terms. For anyone tracking British television talent, her pivot from actress to filmmaker is the most telling signal: she is not resting on a 18-year legacy, but actively expanding it. For the curious viewer, the choice is clear: follow her directing credits, because the best may still be ahead.
