Phantom of the Opera Easter Egg - Three Eggs

I didn't want to go through the process of submitting these eggs separately, so I put them all together.

Egg #1- True fans of this movie know that Carlotta, played by Minnie Driver, is the only cast member that doesn't sing her part in the movie. The woman who sings for Carlotta, Margaret Preece, was allowed a cameo in the movie. In the scene "Poor fool/Il Muto", the woman in the purple dress singing about the youth that set her lady's heart aflame is Margaret Preece, Carlotta's singing voice.

Egg #2- The music box with the monkey in Persian robes is most likely a reference to the novel by Gaston Leroux, which the movie is based on. The character that helps Raoul rescue Christine is called The Persian.

Egg #3- This is possibly not an Easter Egg, but it took me about twenty viewings to spot. During the final scene where Raoul and Christine are in the Phantom's lair, after the Phantom says, "You try my patience. Make your choice!" Christine looks at Raoul and mouths the words, "I love you" to him, then sings, "Pitiful creature of darkness, what kind of life have you known? God give me courage to show you, you are not alone!" I don't know if this is an actual, bona fide Easter Egg or not, but I thought I'd try it anyway.
