This 1971 music is written and directed by Ken Russell, a director famous for his visual excess – yet in this movie, about an understudy of a musical who achieves stardom, those impulses are put to wholly appropriate use. The understudy, played by waifish fashion model Twiggy, not only dreams of stardom, but has fantasies about it – fantasies envisioned through Russell’s particular vision, which here salutes everything from the vintage choreography of Busby Berkeley to some of Russell’s own trademark tricks. Tommy Tune co-stars.
