In 1977, Maughan joined the cast of Franco Zeffirelli's "Filumena", starring Joan Plowright and Colin Blakely in London's West End, where she met her future husband, actor Trevor Eve. Maughan then went on to star in such series as "The Enigma Files", "The Flame Trees of Thika", "Dombey and Son", and "By the Sword Divided". As a result of the success of "The Flame Trees of Thika" in America, Maughan was invited to do an episode of "MacGyver", which was the beginning of her bi-coastal professional relationship.
