Who Is Siân Phillips? A Comprehensive Biography
Dame Siân Phillips, born Jane Elizabeth Ailwên Phillips on 14 May 1933 in the Welsh village of Gwaun-Cae-Gurwen, has built a career that spans more than seven decades. She is known internationally for her portrayal of the cunning Empress Livia in the BBC series I, Claudius and as the Reverend Mother Gaius Helen Mohiam in David Lynch’s 1984 film Dune. Her work has earned her a BAFTA award, a Royal Television Society award, and a damehood in 2016.
Phillips grew up in a Welsh-speaking farming family and did not learn English until she was a child, picking it up by listening to the radio. She began acting professionally at age 11 with BBC Radio Wales. After studying English at Cardiff University, she trained at the Royal Academy of Dramatic Art (RADA). She made her Broadway debut in 1958 as Helena in A Midsummer Night’s Dream.
Her personal life has attracted as much public interest as her career. She was married to the Irish actor Peter O’Toole from 1959 to 1979, a tumultuous relationship that she has said caused her to miss what she called her “Golden Years” between the ages of 29 and 45. She later married British actor Robin Sachs, though that marriage ended in divorce in 1991.
