The original score for Beauty and the Beast was written by Georges Auric, however, in 1995, Philip Glass composed an opera designed to be performed while the film is projected without sound (the vocals are in sync with the lips of the actors onscreen).
Jean Marais in Beauty and the Beast (1946, dir. Jean Cocteau) (via)
“My method is simple: not to aim at poetry. That must come of its own accord. The mere whispered mention of its name frightens it away. I shall try to build a table. It will be up to you then to eat at it, to examine it or to chop it up for firewood.”
-Cocteau, Beauty and the Beast: Diary of a Film (1947)
