The Phantom of the Opera at the Royal Albert Hall is a 2011 British film adaptation of Andrew Lloyd Webber's 1986 musical The Phantom of the Opera, which in turn was based on the 1910 French novel Le Fantôme de l'Opéra by Gaston Leroux. To celebrate the 25th anniversary of the musical, three special performances were filmed at the Royal Albert Hall, the third of which was screened live worldwide on 2 October 2011. For further releases, footage from all three performances was edited together.
