Tales from the Vienna Woods
Thomas' stage credits beginning in the 1940s included a number of roles with the Royal Shakespeare Company during the 1960s in productions directed by Peter Hall, including "The Comedy of Errors", "Richard II", "Richard III", "Henry V" and "Henry VI, Part 2", supporting David Warner, Roy Dotrice, Ian Holm, and Peggy Ashcroft, among others. In 1977, she played a zither as a "venomous elder" in "Tales from the Vienna Woods" at the Royal National Theatre. In 1982, at age 92, she was Marina in Peter Hall's production of "Uncle Vanya". That year, the "Guardian" profiled Thomas under the headline "A National Legend."
