Continuity mistake: The Moment Raoul falls through the trapdoor in the stairs and into the water, you can see the grid (that's coming down later) already in the water. For the grid to come down and drown Raoul, he must have fallen through it. (01:53:35)
Audio problem: In Prima Donna, when Carlotta is on the bed that Andre and Firmin are carrying her on, the words "Prima Donna once more" are sung but Minnie Driver, Carlotta, "sings" the words after the actual words are sung.
Other mistake: When the phantom sings behind Christine's mirror in her dressing room, she starts to walk towards it, entranced. It's obvious he is behind the mirror, and it's a one-way mirror. But, when she touches his hand, wouldn't the mirror have to be opened up? They act like she can just walk into the mirror. (00:30:55)
Suggested correction: When the Phantom begins singing behind the mirror and Christine approaches, it appears as if she walks through the mirror to the other side, then grabs the Phantom's hand. The hallway she is taken into is elaborate, with gold human arms holding candles. Later, when Meg looks for Christine in her room, she finds the mirror odd and slides it open to enter the secret hallway, finding it dark and rat-infested. This proves that what Christine saw was in her mind and that she imagined she walked through the mirror.
Continuity mistake: When Meg finds Christine in the room with all of the candles after her "Think Of Me" performance, she puts her hand on Christine's shoulder, then removes it. In the next shot from behind Christine, Meg proceeds to remove her hand again.
