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.^[1][2] 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.^[3] Following her training, she gained early experience with the Joint Stock Theatre Company, Paines Plough touring, and the Duke's Playhouse, Lancaster.^[4]

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 installments of the BBC's A Dorothy L.

In 2016, Walter played Clementine Churchill on the Netflix series The Crown, appeared in two episodes in 2017 in Call the Midwife and had a recurring role on the HBO series Succession (2018⁠–23). In 2020, Walter joined the series Killing Eve.^[6][7]

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.

Walter was in a relationship with actor Peter Blythe from 1996 until his death in 2004.^[8] She married actor Guy Paul in 2011.^[9]

At the age of 20, Walter became a feminist and went "into political theatre; to try and put as much feminism into the interpretation of parts I was playing".^[10] She was conflicted on her damehood and nearly turned it down,^[11] but eventually decided to accept because "there are many fewer women [than men] who can sustain a career to the point where they can be named a dame, and that's not through lack of talent. It was a slightly political gesture".^[12] She supported the UK remaining in the European Union in the run-up to the 2016 EU referendum.^[13]

Walter, who speaks Russian, performed a reading at the 2022 Poets for Ukraine event alongside the likes of Juliet Stevenson and Meera Syal.^[14] In light of the 2023 Israel–Hamas war, Walter was one of over two thousand to sign an Artists for Palestine letter calling for a ceasefire and accusing western governments of "not only tolerating war crimes but aiding and abetting them."^[15] She condemned the decision to rescind Caryl Churchill's 2022 European Drama Lifetime Achievement Award over Churchill's support of Palestine and alleged anti-semitism.^[16]

Walter is a patron of the Shakespeare Schools Festival, a charity that enables school children across the UK to perform Shakespeare in professional theatres; Prisoners Abroad, a charity that supports Britons imprisoned overseas and their families; and Clean Break, a charity and theatre company dedicated to sharing the stories of imprisoned women and transforming the lives of female offenders through theatre education.^[17]
