Kelly Reilly Education
Reilly attended Tolworth Girls’ School in Kingston, Surrey, where she studied drama as part of her General Certificate of Secondary Education (GCSE). Drama was the subject that gave the shy, reserved young Reilly her confidence.
She never enrolled in a formal drama school. Instead, she developed her craft through a weekly performers’ showcase in London. That weekly showcase earned her an agent — and set her career in motion.
Kelly Reilly Career
Reilly began pursuing acting as a teenager through pure persistence. At 16, she wrote letters to the producers of the acclaimed police drama Prime Suspect, requesting a role.
Six months later, she auditioned successfully and landed a guest role in Prime Suspect 4: Inner Circle, broadcast on ITV on May 7, 1995. That same year, she appeared in the short-lived drama series The Biz.
Her first professional role was quickly followed by a series of stage parts on the English stage.

Johnson wrote Piano/Forte entirely for Reilly. He described her as “the most natural, dyed-in-the-wool, deep-in-the-bone actress I’ve ever worked with.”
Her biggest stage breakthrough came in 2003 with After Miss Julie at the Donmar Warehouse in London.
That performance earned her a Laurence Olivier Award nomination for Best Actress of 2003. At age 26, she became the youngest person ever nominated in that category.
She credited director Karel Reisz — who helmed her in The Yalta Game in Dublin in 2001 — as her most important mentor. In her own words, “He was my masterclass.”
By 2009, Reilly had earned a second Olivier nomination for her portrayal of Desdemona in Othello at the Donmar Warehouse.
In 2015, she made her Broadway debut in Harold Pinter’s Old Times at the American Airlines Theatre opposite Clive Owen.
