Harriet Walter

Walter was born in London, England. She is the niece of British actor Sir Christopher Lee, being the daughter of his elder sister Xandra Lee. On her father's side, Walter is a great-great-great-great-granddaughter of John Walter, founder of The Times. She was educated at Cranborne Chase School. After turning down a university education, she was rejected by five drama schools before being admitted to the London Academy of Music and Dramatic Art. Following her training, she gained early experience with the Joint Stock Theatre Company, Paines Plough touring, and the Duke's Playhouse, Lancaster. Walter worked with Royal Shakespeare Company (RSC) productions Nicholas Nickleby (1980), A Midsummer Night's Dream (1981), All's Well That Ends Well (1981), The Castle (1985), A Question of Geography, Twelfth Night (1988), Three Sisters (1988), The Duchess of Malfi (1989), Macbeth (1999), Much Ado about Nothing (2002) and Death of a Salesman (2015).

In 1987, Walter was made an associate artist of the RSC. Additional theatre work includes Three Birds Alighting on a Field (1991), Arcadia (1993), Hedda Gabler (1996), Ivanov (1997) and Mary Stuart (2005).

Walter made her Broadway debut in 1983, when the RSC production of All's Well That Ends Well transferred there. In 1993, she starred as Biddy in the off-Broadway production of Three Birds Alighting on a Field, for which she received a Drama Desk Award nomination. She returned to the Broadway stage in 2009, when she reprised her role in Mary Stuart. In 2014, Walter starred as Brutus in an all-female off-Broadway production of Julius Caesar and received her second Drama Desk nomination.

Walter's films include Sense and Sensibility (1995), Bedrooms and Hallways (1998), The Governess (1998), Onegin (1999), Villa des Roses (2002) and Bright Young Things (2003). In 1987, she portrayed Harriet Vane in three instalments of the BBC's A Dorothy L. Sayers Mystery, and played Detective Inspector Natalie Chandler from 2009 to 2012 in the ITV drama series Law & Order: UK. Other television roles include Waking the Dead (2001), Little Dorrit (2008), A Short Stay in Switzerland (2009) and Lady Shackleton in four episodes of the series Downton Abbey (2013–15).

Walter played Brutus in Julius Caesar in 2012, and the title role in Henry IV in 2014, in all-female productions at the Donmar Warehouse. Both productions transferred to Brooklyn's St. Ann's Warehouse in New York. She was set to reprise both roles, as well as playing Prospero in an all-female production of The Tempest, as part of director Phyllida Lloyd's Shakespeare trilogy at the Donmar's temporary, in-the-round, 420-seat theatre next to King's Cross station in 2016.
