The star has injured an ankle, but the show - and inexperienced stage assistant Polly Browne - must go on. Break a leg, kid. And don't let the presence of Hollywood director and talent scout Mr. de Thrill add any pressure. And so begins this colorful tale of theater hopefuls with stars in their eyes and greasepaint in their veins, a work that, under the guidance of director Ken Russell, is not just an affectionate filmization of Sandy Wilson's London/Broadway stage hit but also an homage to the movie stagings of Busby Berkeley - complete with imaginative use of kaleidoscopic top shots and rows of leggy chorines. Fashion icon Twiggy makes her screen debut as sweet-natured Polly, a role played earlier by Julie Andrews in her Broadway debut. Curtain up. Maybe someone will be discovered tonight.
