Cats is a 1998 British direct-to-video musical film based on the 1981 stage musical by Andrew Lloyd Webber, itself based on Old Possum's Book of Practical Cats (1939) by T. S. Eliot. Lloyd Webber oversaw orchestration and called on Gillian Lynne, the show's original choreographer, to train the cast members. David Mallet served as the director of this production. The film is a recreation of the stage musical, but with new staging and significant edits made to reduce the runtime for television broadcast. It was filmed at the Adelphi Theatre in London in 1997, with the cast selected from various past and (then) present international productions of Cats. Initially released to VHS and subsequently DVD and Blu-ray, the film has since been shown on television channels including PBS, BBC and Ovation TV. Source: Wikipedia (en)
