Maddie’s career started at the tender age of 10 in Greg Davies’ sitcom Man Down. She quickly progressed to a series regular role in the children’s comedy Hank Zipzer with Henry Winkler, and the Professor Branestawm film series, starring alongside Harry Hill as his young apprentice.

As well as on-screen comedy, Maddie has appeared in dramas including The Queen’s Gambit (2019) as Shirley Munson, The Durrells (2018) and has expanded her film work with roles in Home Sweet Home Alone (2020) as Katie Mercer and How To Date Billy Walsh (2022) as Maddie.

Her stage career began in 2021 at the National Theatre in Jack Thorne’s After Life, and she soon took on the role of Rosie in Steven Moffatt’s farce The Unfriend, which premiered at Chichester Festival Theatre in 2022 and enjoyed record-breaking transfers to the West End in 2023 (Criterion Theatre) and 2024 (Wyndham’s Theatre), all under the direction of Mark Gatiss.

Playing the daughter of comedians including Lee Mack, Aisling Bea, and Reece Shearsmith, and working under the direction of Mark Gatiss, Maddie has embraced every opportunity to learn from the remarkable talents around her.

Of her time on Hank Zipzer, Henry Winkler wrote in his autobiography: “Maddie Holliday was Hank’s annoying younger sister, she was ten at the time, and this was one of her very first acting jobs. During a scene in the pilot, I threw her an ad lib as I exited, and she threw an ad lib right back, as if she’d been doing it for years.”
