The Phantom of the Opera is a 2004 film adaptation of Andrew Lloyd Webber and Charles Hart's 1986 stage musical, which is based on the novel of the same name by Gaston Leroux. The film was written and directed by Joel Schumacher and Webber and Webber produced the film. The cast includes Gerard Butler as the Phantom, Emmy Rossum (who was only 17 at the time of filming) as Christine Daaé, Patrick Wilson as Raoul, Vicomte de Chagny, Miranda Richardson as Madame Giry, Jennifer Ellison as Meg Giry, and Minnie Driver (whose vocals were dubbed by Margaret Preece, a professional opera singer) as Carlotta Giudicelli. Ramin Karimloo (who had been playing Raoul in the London production of Phantom at the time of filming) appeared in a cameo role as Christine's father.

The film was a USA/UK co-production that had various distributors worldwide. For example, Warner Bros. (a main production partner) distributed the film in the USA, and Universal Pictures (producers and/or distributors of the 1925, 1943, and 1962 adaptations of the book) released the film in Latin America and Australia.
