A natural performer, she joined a children's drama class for an hour every Saturday afternoon where her love for acting soon shone through. Before long, Matilda began winning roles in commercials, TV shows, and movies. Her first lead role came at only six years old when she starred in McDonald's 2021 UK Christmas commercial directed by Bert and Bertie. In 2022, Matilda had roles in Disney's "Disenchanted", "Vampire Academy", "Christmas Carole", and "Starve Acre". She also filmed the role of Grace in "Hullraisers". The following year, Matilda completed the movie "Subservience", starring Megan Fox, and played Nancy in the highly acclaimed BBC show "Time". Later that year, she got the roles of both Sophie in "Coma" and Mille-Jo in the groundbreaking "Mr Bates vs. The Post Office." In 2024, Matilda joined the cast of Blumhouse and Universal's "Wolf Man", as well as "Nine Perfect Strangers". Matilda is represented by Paradigm Talent Agency (USA) and Articulate Agency (UK).
