Fiona Shaw is one of the most respected stage actresses of her generation, an Irish performer whose work at the Royal Shakespeare Company and National Theatre, including a celebrated turn as Richard II (1995), established her reputation long before television introduced her to a wider audience. She appeared in My Left Foot (1989) and the Harry Potter franchise as Aunt Petunia Dursley beginning in 2001, then found a new generation of fans as the icy MI6 handler Carolyn Martens in Killing Eve (2018), earning an Emmy nomination for the role.

On screen, Shaw operates through a sharpness that makes even brief appearances feel loaded with weight, a quality Killing Eve used for both comedy and menace within the same scene. Her angular features, brunette hair, and clipped delivery give her a presence that feels formidable in any role, from the comic suburban cruelty of Aunt Petunia to Carolyn’s lethal composure. She remains one of the most accomplished performers working across stage and screen.
