In one of the 1919 flashback scenes, Raoul looks out of the car window at a Swarovski jewelry store. The Swarovski crystal company made the chandelier for the film, valued at over $1.3 million.

The candles that light instantly as they come out of the water in the Phantom's Lair were not done by computers- special candles were used that were sensitive to air. Luckily, the scene went well and the actors didn't mess up, as when they tried to re-shoot the scene, the candles didn't work a second time.

Since the camera angles during "All I Ask of You" are sweeping, the kiss between Christine and Raoul had to be shot many, many times. Emmy Rossum had to ice her lips between takes to keep them from swelling.

In the beginning, when the Phantom leads Christine down a passage, the moving arms holding candelabras are a tribute to Jean Cocteau's 'Beauty and the Beast,' filmed in 1946.

The song sung during the credits is song by Minnie Driver who played La Carlotta. Hers were the only vocals dubbed during the movie.

In Carlotta's dressing room there is a large portrait of Carlotta holding Andrew Lloyd Webber's head on a plate.

This movie was originally going to be made in 1990 with Sarah Brightman and Michael Crawford in the leading roles, the same actors who played the parts originally on stage. However Brightman's divorce from composer/producer Andrew Lloyd Webber put an end to the project.
