Redgrave's first professional stage work was as director of "The Scarecrow" at the Royal Court Theatre in London, and by the next year he was an acting, as Lysander in the Royal Court's production of "A Midsummer Night's Dream". By 1963, he had crossed the Atlantic to appear on Broadway in a supporting part in "Chips With Everything". Redgrave's feature film work began with a turn as Roper in Fred Zinnemann's "A Man for All Seasons" in 1966. Many of his other film roles have been in decidedly British works, such as the remake of "The Charge of the Light Brigade" (1968), directed by then brother-in-law Tony Richardson, and Sir Richard Attenborough's heralded "Oh, What a Lovely War" (1969). After many years spent concentrating on politics in his native land, Redgrave turned his attentions back to acting. He was the nemesis Robert Dixon in "In the Name of the Father" (1993) and Hamish, whom Andie MacDowell marries, in "Four Weddings and a Funeral" (1994). Redgrave's TV appearances have been sporadic, most notably as Steerforth in "David Copperfield" (NBC, 1970) and Octavius in "Antony and Cleopatra" (BBC, 1975).
He is the son of the late Sir Michael Redgrave and Rachel Kempson and brother of Vanessa and Lynn. Redgrave's daughter Jemma is an actress and his son Luke is a cameraman. In 1994, Redgrave joined his sister Vanessa in founding the Moving Theatre Company.
