The legend of Tristan and Isolde, like many old tales, is shrouded in mystery. There were many versions of this story before the invention of film, and many more thereafter. But there don’t appear to have been any significant English-language films about these doomed lovers since the early 1980s, when two such films appeared almost simultaneously. One, Lovespell, starred Richard Burton as King Mark and Kate Mulgrew, now best known as the prickly Captain Janeway on Star Trek: Voyager, as his adulterous wife Isolde. Her lover, Tristan, was played by Nicholas Clay, who seems to have had a monopoly back then on conflicted, amorous knights; that same year, he also played Sir Lancelot in Excalibur.
