What is Caroline Catz doing now after Doc Martin?

Recent acting roles

Following the end of Doc Martin in 2022, Catz took on the role of Auguste van Pels in the Disney+ limited series A Small Light (Independent Talent Group, her talent agency). She also returned to the stage at the Marylebone Theatre in What We Talk About When We Talk About Anne Frank (Independent Talent Group).

Directing and writing projects

Catz wrote, starred in, and directed the feature documentary Delia Derbyshire: The Myths and Legendary Tapes, which won the Adam Yauch Special Jury Prize at SXSW (Independent Talent Group). The project cements her move behind the camera.

Narration and documentary work

She has narrated documentaries for BBC, Channel 4, and ITV, including Putin Vs The West and Trump Takes on The World (Independent Talent Group).

The shift from a single iconic role to a varied portfolio underscores her determination to control her own career direction.

What is Caroline Catz’s real name?

Birth name and legal name

Caroline Catz was born Caroline Caplan on 19 October 1969 in Manchester, England (Wikipedia, the free encyclopedia). She trained at the Royal Academy of Dramatic Art (RADA) before beginning her professional career (IMDb, the film database).

The implication: her stage name is a deliberate professional choice, not a married name or a publicity stunt.

Why did Caroline Catz change her name?

Professional reasons

According to her IMDb biography, Catz changed her surname from Caplan because the name was already registered with British Equity by another actress (IMDb bio). She reportedly chose “Catz” after seeing a doodle of a cat (IMDb bio). The content plan also notes that Catz is a variation of her father’s nickname, though that detail is not independently verified.

Personal choice

Whatever the exact origin, the name has stuck for three decades. It is the name under which she has built her entire public career.

The uncertainty around the name’s origin adds a layer of mystery to her public persona.

What religion is Caroline Catz?

Public statements

Caroline Catz has never publicly disclosed a religious affiliation. In extensive coverage of her career and personal life, no mention of faith appears (Wikipedia; IMDb).

Private beliefs

Because Catz maintains a notably private personal life, no verified information about her religion exists. The absence of evidence is not evidence of absence, but it remains a blank in the public record.

The lack of public information reflects her strong preference for privacy.

Who is Caroline Catz’s husband?

Marriage to Michael Higgs

She married actor Michael Higgs in 1997 (IMDb). The couple met on the set of the long-running police drama The Bill (Wikipedia). Higgs is known for his roles in EastEnders, The Bill, and other British television series.

Family life

Catz and Higgs have two children, Sonny-Joe Caplan-Higgs and Honor-Ray Caplan-Higgs (IMDb bio). The family maintains a low public profile, and Catz rarely discusses her children in interviews.

Why this matters: in an era of oversharing, Catz’s decision to keep her family out of the spotlight is itself a statement – and one that aligns with her preference for letting her work speak for itself.
