Growing Up in a Creative Family
Mackintosh Muggleton was born on February 16, 1994, in London, England. Most people who know him just call him “Mack.” That is his everyday nickname, not a stage name.
Public details about his childhood are limited. He grew up in London, a city with a long history in film and theater. This may have given him early exposure to the kind of creative world his family already worked in.
Not much has been shared about his siblings, his schooling, or his exact upbringing. Mack has kept a low profile for most of his life outside of acting. He has not spoken publicly in detail about his education, and no verified information is available about that part of his life.
What is clear is his early move toward acting. He got his first big role as a young teenager. This meant he entered the entertainment industry early and quickly.
His Mother’s Oscar-Winning Career
Mack’s mother is Sarah Greenwood, a well-known British production designer. She has built her career by designing the look and feel of major films. She worked closely with director Joe Wright on movies like Pride & Prejudice, Atonement, and Anna Karenina. She has also worked on Sherlock Holmes, Beauty and the Beast, Darkest Hour, Cyrano, and Barbie.
Sarah Greenwood has received several Academy Award nominations for Best Production Design in her career. She also won a BAFTA Award for her work on Atonement. She is widely respected in the film industry for her detailed, immersive set designs.
Growing up with a mother who works at this level of filmmaking likely gave Mack an early window into how movies are made. While he has not spoken at length in public about how this shaped his own path, it is easy to see the family’s connection to the film industry running through his career. Information about his father has not been made public, and Mack appears to keep that part of his life private.
How Mackintosh Muggleton Started His Acting Career
Mack did not spend years working through small roles before his big break. Instead, his very first credited acting role was also his breakout one. He was cast in 28 Weeks Later, a major horror sequel, while he was still young.
There is no widely available record of early auditions, small television appearances, or minor film roles before this. Public sources point to 28 Weeks Later as his acting debut. This means Mack went almost straight from being a newcomer to being part of a film that reached audiences around the world.
After this early breakthrough, his career slowed down in terms of acting credits. He later chose to focus on short films and independent projects instead of mainstream roles. This path is different from what many child actors do.
Mackintosh Muggleton in 28 Weeks Later
In 28 Weeks Later (2007), Mack played Andy Harris. This was a key role in the film, which is set in London during a terrifying outbreak caused by the “rage virus.” Andy is one of two children at the center of the story, alongside his older sister Tammy, played by Imogen Poots.
The plot puts Andy in constant danger. As the infection spreads again, Andy and Tammy must survive. They are surrounded by infected adults, even some from their own family. This included a tense and emotional storyline involving Andy’s father, played by Robert Carlyle.
The role became well known because it asked a young actor to carry real emotional weight in a frightening, high-stakes story. Critics and horror fans noticed Mack’s performance, especially for someone acting at such a young age in his very first film role.
The impact on his career was immediate. 28 Weeks Later became the project most people connect with his name, even years later. It also placed him inside the 28 Days Later franchise, a series that horror fans continue to follow closely, including ongoing interest in whether Andy’s story could ever continue in a future installment.
Mackintosh Muggleton Movies and TV Shows
Mack’s on-screen credits are not large in number, but they span more than one decade. His filmography includes:
- 28 Weeks Later (2007) — his acting debut, playing Andy Harris in the horror sequel that put him on the map.
- The Man in the Mist (2016) — an independent short project where Mack worked as both a director and an actor, marking his move behind the camera.
- Salem Witch Doll (2024) — a supernatural horror short in which Mack played a character named Kieran, centered around a cursed doll.
Beyond these credited film roles, Mack has appeared in some promotional and interview segments tied to 28 Weeks Later, including early television appearances discussing the film. There is no confirmed record of him taking on other major film or television roles between his 2007 debut and his return to short filmmaking years later. This gap suggests he stepped back from mainstream acting for an extended period before working on independent projects again.
Mackintosh Muggleton Work Beyond Acting

Specific details, such as where he performs, his musical style, or particular releases, are not widely confirmed through reliable sources. As with some other parts of his personal and professional life, Mack has kept this side of his work relatively low-key and out of major media coverage.
