The Phantom of the Opera (2004 film)

The film was announced in 1989 but production did not start until 2002 due to Lloyd Webber's divorce and Schumacher's busy career. It was shot entirely at Pinewood Studios, with scenery created with miniatures and computer graphics. Rossum, Wilson and Driver had singing experience, but Butler had none and so had music lessons. The Phantom of the Opera grossed $154.6 million worldwide and received mixed to negative reviews from critics, but was very well received by audiences. Critics praised the visuals and acting (particularly Rossum's performance) but criticized the writing and directing.
