Antonia’s career started with a bang after she won the role of Alisha in the BAFTA-winning television series Misfits just one day after graduating from Bristol Old Vic Theatre School.  After leaving Misfits, she went on to star in the Netflix cult favourite Lovesick, earning praise for her natural wit and emotional depth and has since built up an eclectic body of work starring in highly acclaimed television drama, feature films and theatre. 

Currently starring as Tuppence in Agatha Christie’s Tommy & Tuppence (2026) on Britbox, Antonia is most widely known for her role opposite Feddie Highmore as Dr. Claire Browne in the hit ABC series The Good Doctor (named the Most Watched Television Drama in the world in 2018-2019). She also appeared in Steve McQueen’s acclaimed anthology Small Axe (BBC/Amazon) alongside John Boyega, and starred as Lisa in the Apple TV+ comedy-drama Still Up. Antonia was most recently seen as a lead in the BBC series Two Weeks in August and the comedy feature Preschool, directed by Josh Duhamel.

Antonia’s previous feature film credits include the BAFTA-nominated British indie Northern Soul; James McTeigue’s international action thriller Survivor, working alongside Milla Jovovich and Pierce Brosnan; and the hugely popular musical Sunshine On Leith which garnered fantastic reviews and an Empire Awards Nomination for Antonia as Best Female Newcomer.

With a host of independent British features behind her, sell-out runs at the National Theatre with acclaimed and inspiring production Home, and multiple stand-out roles in some of the most popular UK drama series, Antonia continues to be one of Britain’s most dynamic acting talents.
