Twiggy's second feature, the thriller "W" (1974) paired her with future husband Michael Witney, and she later appeared in a small role in "The Blues Brothers" (1980) and played a would-be singer in "Madame Sousatzka" (1988, opposite second husband Leigh Lawson), among her other pictures. Though she worked in TV both at home in England and on CBS' short-lived sitcom, "Princesses" (1991), she has made her biggest impact on stage, beginning with her West End debut as "Cinderella" in 1974. In 1983 she reunited with her "Boy Friend" co-star Tommy Tune who was co-directing and starring in Broadway's "My One and Only", a reworking of the 1920s Gershwin classic "Funny Face". Acting in a 1997 London revival of Noel Coward's "Blithe Spirit" was the first step on the way to playing what may turn out to be a defining role of her career, that of Coward's platonic flame and frequent co-star Gertrude Lawrence. Of Lawrence, Agnes de Mille once said, "She can't sing, but who cares?", and Twiggy brought the same kind of star presence to her off-Broadway turn in "If Love Were All", a musical telling of the famous friendship to the accompaniment of 20 Coward songs.
