She also received a BAFTA Television Award nomination for Best Female Comedy Performance in Plebs in 2014 (Wikipedia).

The implication: Mackichan’s transition from ensemble sketch work to long-running sitcom roles shows her versatility across genres.

What Is Doon Mackichan’s Background?

Early life and education

She was born Sarah Doon Mackichan on 7 August 1962 (IMDb) and raised in the UK. Details about her schooling are not widely published, but she entered the entertainment world through stand-up comedy in the 1980s (Wikipedia).

Career start in stand-up comedy

Mackichan began performing stand-up in the 1980s, a period when female comedians were still rare on the circuit. Her sharp timing and willingness to push boundaries quickly caught the attention of comedy producers. She joined the writing teams of The Day Today (1994) and Brass Eye, working alongside Armando Iannucci and Christopher Morris (BBC). That path eventually led to her own show, Smack the Pony.

The pattern: her early work in alternative comedy provided the foundation for her later mainstream success.

Is Doon Mackichan English?

Nationality and heritage

Yes, Doon Mackichan is British. She was born in the United Kingdom and identifies as a British actress and comedian (Wikipedia). Her full name, Sarah Doon Mackichan, suggests Scottish or Gaelic roots (the surname Mackichan is of Scottish origin). No contradictory information about her nationality appears in any credible source.

Why Did Doon Mackichan Leave Two Doors Down?

Character Jaz written out

Mackichan played Cathy Whyte (often called Jaz) in Two Doors Down from 2013. In 2022, her character was written out of the show, though she later returned for a guest appearance (Radio Times (TV listings magazine)). The Independent reported that she had played the role for a decade between 2013 and 2023 (The Independent (UK news outlet)).

Behind-the-scenes reasons

Exactly why the writers decided to phase out Cathy is not publicly confirmed. Mackichan herself has said there were scenes in Two Doors Down that she refused to film, according to an interview quoted by The Independent. That suggests a creative difference over material she found uncomfortable. The BBC and producers have not issued a detailed statement about the decision.

What this means: the departure underscores how even long-running sitcoms can face behind-the-scenes tensions over content boundaries.

What Is Doon Mackichan Doing Now?

Recent projects and appearances

Mackichan continues to work in television and theatre. One of her most public recent appearances was on The Great Sport Relief Bake Off in 2016 (IMDb). She also returned to the stage in 2019 for David Mamet’s Bitter Wheat, starring alongside John Malkovich. Michael Billington of The Guardian called Mackichan’s performance the best in the show (IMDb).

Voice work and future outlook

She remains active in voice acting and has expressed interest in developing new writing projects. Mackichan lives in South London with her three children (BBC). No major new series has been announced as of early 2025, but her long track record suggests more roles are likely.

The catch: her next major television role may need to come from a creator who values artistic boundaries as much as comedic timing.
