The Phantom of the Opera is a 2004 musical romantic drama film based on Andrew Lloyd Webber's musical of the same name, which in turn is based on Gaston Leroux's novel, Le Fantôme de l'Opéra. Produced and co-written by Lloyd Webber and directed by Joel Schumacher, it stars Gerard Butler as the titular character, with Emmy Rossum, Patrick Wilson, Miranda Richardson, Minnie Driver, Simon Callow, Ciarán Hinds, Victor McGuire and Jennifer Ellison in supporting roles.

The film was announced in 1989, although 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 was provided with music lessons prior to filming. The Phantom of the Opera grossed $154.6 million worldwide. It received mixed reviews from critics, with praise for the visuals and acting, particularly the performances of the lead actors, but criticism towards the writing, direction and unnecessary deviations from the stage version.
