Corrected entry: When Raoul leaves Christine's dressing room after her performance in 'Hannibal', the phantom locks her door. But then later, when Meg comes look for her, she opens the door without difficulty. (00:41:20)
Corrected entry: On the opera house's rooftop, Christine, sick with worry and fear, decides to run away with Raoul right after the performance so that he can hide and protect her from the Phantom, and tells him to prepare his horses so they can leave right away. Then nothing happens. We're brought three months forward to the masquerade and no mention is ever made again of what happened to change their minds and why they did not run away. If she is scared enough to want to run away right away, not even waiting until the next day to pack her things, there is no way that she'll feel comfortable and safe enough to come back within a mere three months. While in the stage show, that was due to the hubbub surrounding the chandelier crashing, that event was pushed back later in the movie, leaving a gaping hole in the plot.
Correction: Nothing suggests that they didn't run away and then return three months later. There could be any number of reasons; Raoul doesn't believe in the Phantom at this point so perhaps he was able to persuade Christine to come back with him. Maybe Christine felt safer once she and Raoul were engaged. No one at the opera has heard from the Phantom for some time so they asked Christine to attend the Masquerade. Audiences would be anxious to hear Christine perform again so maybe that would be enough of a draw to prompt her to return.
Corrected entry: When Firmin and Andre are reading their letters from the Phantom to each other, their mouths don't match up with the audio.
Correction: This is incorrect. The mouths do synch with the audio.
Corrected entry: In Think of Me,on the "Ah,ah,ah,ah,Ahhh's" you can see Emmy Rossum's gum on the left(her left)side of her mouth when they have a close up.
Correction: Sorry, but all the rumors of Emmy Rossum having gum in her mouth during filming are just absurd. A picture of the shot in question is needed for this mistake to be legitimate.
Corrected entry: When the Phantom sings, "So do you end your days with me, or do you send him to his grave," his teeth are clenched as he sings "me" which is not possible.
Correction: Rubbish. I just did it several times with no problem (and no formal training as a singer).
Corrected entry: If Gustav Daaé died leaving his daughter in utter poverty, why is he buried in the largest mausoleum (which, presumably, cost the most) in the cemetery? It can't be a family mausoleum, since he's Swedish, not French, and the only reason Christine remained in France is because he died.
Correction: No-one in the movie says anything about "utter poverty", that's an assumption. Christine might have inherited some money from him, and besides, at the time most succesful artists had patrons in the form of admirers. One of these might have been a big enough admirer of Daaé to have paid for a grand mausoleum, as a tribute.
Corrected entry: During Don Juan, when the Phantom and Christine go up the scaffolding during the song "Point of No Return," round bolts are seen in the wood. It should have square nails holding it together because there were no round bolts in 1870.
Correction: The "History of the Nut and Bolt Industry in America" by W.R. Wilbur in 1905 acknowledges that the first machine for making bolts and screws was made by Besson in France in 1568. - From http://www.nord-lock.com/bolted/the-history-of-the-bolt/.
Corrected entry: When the Phantom threatens to hang Raoul, after he says "You try my patience. Make your choice." and chokes Raoul once again, Raoul doesn't have a rope around his neck, he just acts the part.
Correction: Raoul does have the rope around his neck, the noose's knot is just behind his head.
Corrected entry: When Carlotta starts to sing "Think Of Me" she lifts her chin when singing the high note at "you'll". Classical singers are taught from the very beginning of their education that the chin is to be dropped, not lifted, when singing high notes.
Correction: Carlotta is the sort of woman who does things her way, even if it isn't the proper way to do it. It's not really a mistake; it's just Carlotta being Carlotta.
Corrected entry: After Phantom has killed Buquet, Christine and Raoul run several floors up to the roof of the opera house. They are both singing, and Christine is wearing corsets, but when they get to the roof, neither of them is out of breath.
Correction: So she is in really good shape.
Corrected entry: In Masquerade, the "gold people" are near the top of the stairs. They are not supposed to move, and if they were to, it would be noticable. But when the Phantom comes up, they are now moved to the bottom of the staris.
Correction: Yes, the "gold people" are situated at the top of the stairs during the beginning of the Masquerade, but the last time we see them at the top is at the end of the part where Andre, Firmin, Carlotta, Piangi, Meg, and Madame Giry are singing, right after we switch to Christine and Raoul who are noticably not in the main room where the "gold people" are, and we watch them for about 30 seconds. That is enough time for the "gold people" to have moved down to the bottom of the stairs. And you will notice that when Christine and Raoul begin to dance that the "gold people" are down there and that is long before the Phantom appears.
Corrected entry: In the scene where the Phantom sings "stranger than you dreamt it", the shot right before it shows the mannequin of Christine, the Phantom says "oh Christine" but his lips are saying something else. (00:46:20)
Correction: His lips are saying "Oh Christine" just as they're supposed to. It might appear to look different at a glance because his lips move drastically to pronounce the letter "s" in "Christine"(due to intense emotion his speaking is slightly stressed) and his chin moves down when transitioning from the letter "s" to the "tine" part, making it seem as though he has mouthed too many syllables for that one phrase. But when you watch it several times you can see that he is saying "Oh Christine."
Corrected entry: In the graveyard scene Christine enters with her hair covered with a shawl. In the next shot the shawl is over her shoulders.
Corrected entry: During the rooftop scene, Christine is clad in a flimsy, sleeveless dress, barely covered by a shawl, yet she doesn't seem to be cold at all.
Correction: She is wearing a floor-length cloak, and the fact that she ran to the roof would have given her enough adrenaline to keep warm. Not to mention the tension/ apprehension of all that occurs on the roof.
Corrected entry: In the Don Juan opera, just after Carlotta's solo, she and the chorus sing their final chord as they point into the audience. The camera moves across towards centre stage. Minnie Driver, obviously thinking she is out of shot stops singing, laughs and jokingly fights for position with the man standing next to her.
Correction: Minnie Driver doesn't get out of character at all, and doesn't laugh. This is Carlotta being Carlotta, bossing people around, scowling at and pushing the man, trying to upstage everyone and take up the spotlight in spite of having lost the main role in Don Juan to Christine. This bit you mention is very reminiscent of "Prima Donna," where she swats people around her.
Corrected entry: The chandelier is gaslight. When it breaks off and falls from the ceiling, the gas should have been disconnected. Instead of burning brightly all the way to the floor and starting a fire, it should have gone out and plunged the theatre into darkness. This is what happened in the real Paris Opera house, in the original book, and on the Broadway version. Only in the movie is the chandelier capable of starting a fire after being disconnected.
Correction: Nowhere in the movie does it say (or show) that it's a gaslight chandelier (only the stage lights are shown to be gas-powered). In fact, it very much looks like candlelight all over. A candlelight chandelier would act just as it did in the movie, setting everything on fire.
Corrected entry: Throughout the movie, especially when the Phantom sing to Christine on the way to his lair, synthesizers and electric guitars are used. These were not yet invented.
Correction: This is part of the movie score and it's definitely not intended to convey that these instruments are somehow being played nearby.
Corrected entry: When Raoul falls through the trapdoor his hair is down, also when he is in the water. However when we see him climbing out of the water his hair is tied back. There is no way he would have tied it back whilst underwater trying not to drown.
Corrected entry: When Meg Giry enters the Phantom's Lair and wades through the water to step up to the grotto, we see the mirrors that the Phantom just smashed with the candlestick intact.
Correction: You are mistaken, they are still smashed.
Corrected entry: In the "Masquerade" scene, there is an up close shot of a female dancer who is lined up on the stairs and is dressed in black, wearing a black mask, and holding a fan. The shot lasts for a couple of seconds, but if looked at closely the girl is Emmy Rossum. In this shot, Rossum looks to her left, covers her face with her fan, looks to her right, covers her face with her fan, then looks directly into the camera. You can recognize Rossum by her distinctive mouth.
Correction: Seeing as everyone in this scene is wearing a mask and you base this entirely on the person's mouth, there is no possible way to say who the woman is.
Correction: When Meg goes to Christine's dressing room you can see she had a key to unlock the door. She places them on a table before heading to the mirror.
