The acting career of Gayle Hunnicutt, who has died aged 80, could be defined in two acts. As an up-and-coming starlet in Hollywood she was often cast for her stunning beauty. Then, after marrying the British actor David Hemmings, she moved to the UK, where she played big parts in two major television series, The Golden Bowl (1972) and Fall of Eagles (1974).
After a divorce she married the journalist and editor Simon Jenkins, and alongside her acting career became a fixture of the British social scene. She may, though, be best remembered for the final three seasons of Dallas, from 1989 to 1991, in which she played Vanessa Beaumont, an English aristocrat whose long-ago affair with JR Ewing produced a son he had never known existed.
