Kelly Reilly

Kelly Reilly (also known as Jessica Kelly Siobhán Reilly) is an English screen and stage actress born on July 18, 1977, in Surrey, England. Celebrated for her intensity and emotional precision, she built a reputation moving seamlessly between prestige theatre and international cinema.

Reilly became a standout on the London stage with her acclaimed turn in After Miss Julie at the Donmar Warehouse, a performance that brought her a 2003 Laurence Olivier Award nomination for Best Actress—making her, at 26, the youngest nominee in that category’s history.

Her film breakthrough followed soon after: she earned the Cannes Film Festival’s Best Newcomer honor in 2005 for playing Wendy in Russian Dolls, after first appearing as the character in The Spanish Apartment. Reilly’s notable credits also include Sherlock Holmes (Mary Morstan), Pride & Prejudice (Caroline Bingley), Mrs. Henderson Presents, The Libertine, The Safe House, and Puffball.
