<P> Maria Björnson designed the sets and over 200 costumes, including the elaborate gowns in the "Masquerade" sequence . Her set designs, including the chandelier, subterranean gondola, and sweeping staircase, earned her multiple awards . Hal Prince, director of Cabaret, Candide, Follies, and Lloyd Webber's Evita, directed the production, while Gillian Lynne, associate director and choreographer of Cats, provided the integral musical staging and choreography . </P> <P> A preview of the first act was staged at Sydmonton (Lloyd Webber's home) in 1985, starring Colm Wilkinson (later the star of the Toronto production) as the Phantom, Sarah Brightman as Kristin (later Christine), and Clive Carter (later a member of the London cast) as Raoul . This very preliminary production used Richard Stilgoe's original unaltered lyrics, and many songs sported names that were later changed, such as "What Has Time Done to Me" ("Think of Me"), and "Papers" ("Notes"). The Phantom's original mask covered the entire face and remained in place throughout the performance, obscuring the actor's vision and muffling his voice . Björnson designed the now - iconic half - mask to replace it, and the unmasking sequence was added . Clips of this preview performance were included on the DVD of the 2004 film production . </P> <P> Phantom began previews at Her Majesty's Theatre in London's West End on 27 September 1986 under the direction of Hal Prince, then opened on 9 October .
