Continuity mistake: When Raul is being hanged, he has a booger under his nose. In the next shot, it's gone.
Factual error: In the film, most of the characters don't wear nearly enough stage makeup. In "Think of Me", when Christine is performing in front of a packed auditorium, for example, she would have needed a lot of blush, eyeshadow, eyeliner, etc. just to look "normal" from the audience's perspective. Instead, as you can see by watching the film, she looks pale and washed out.
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.
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.
Answer: During "Point of No Return, " the Phantom shares a stage with the very vulnerable Christine. He is still masked, though it is a mask other than his trademark white face covering. The Phantom is well known as a murderer and an escape artist. This is the the equivalent of a hostage situation. To rush the stage might risk lives, and everyone in the know is proceeding with caution. During the song, we do get glimpses of police moving about, and Raoul and others looking concerned, subtly signaling one another and considering their next move. The stage crew seems confused. The dancers go on with the show. And law enforcement officers await the right moment to advance. It also gives us the opportunity to enjoy a dramatic musical number that rushing the stage would interrupt.
