Actress Susan Hampshire has been cast as Lady Carteret in The Forsytes, playing LadyCarteret in the show, and discusses her role in the 2026 episode of The Forsyttes. The show follows the story of the illustrious Forsyte family in London in 1877, with the main character, Jolyon Forsytte, heir apparent to the family stockbroking firm, Frances Forsyette. Despite their wealth, alliances, and appearances, London’s old money families do not welcome the Forsytte family, particularly Lady Cartere, of the Carteret family. Despite this, Hampshire reveals that she was offered a small part in The Forrestytes and has previously played Fleur ForsyTE in the 1967 adaptation of John Galsworthy's The Forsette Saga.
