The Phantom of the Opera (2004) - 12 major mistakes

Continuity: At the end when Meg steps out of the water, her pants are wet. However, when she enters the bedroom and finds the Phantom's mask, her pants are perfectly dry.

Visible crew/equipment: During The Music of the Night, you can see a camera shadow pass over the Phantom's and Christine's face. It's around the part where he says, 'Let your fantasies unwind'.

Revealing: During the second kiss, you can see behind Gerard Butler's neck (going from under his hair down to his back) the wire of the apparatus used to keep his lower right eyelid pulled down.

Continuity: When Buquet hangs over the scene, you can see Meg screaming along with three other dancers. Four shots later, Meg is still screaming, but the two girls who were to her right (on the left of the screen) are still dancing, as if they haven't seen Buquet yet.

Revealing: As the grating descends on Raoul, in two shots, large bubbles are flowing downwards. It's obvious, the film was reversed.

Factual error: Raoul is the Vicomte de Chagny and he gets called that throughout the movie, even during the auction (which shows he didn't change titles when his parents or his brother died, for example). Yet Christine's tombstone calls her a countess when it should have read viscountess–or, even better, vicomtesse.

Deliberate "mistake": As Christine approaches the Phantom in his lair (just after he has abducted her), we see that she is wearing very dark black eye-shadow. Back in the dressing room after coming off stage, as she talks to Raoul, we saw her face in close up and she was not wearing any eye-shadow at all, even though the Phantom leads her through the mirror just after she has managed to slip on a robe over her undergarments and she has not yet changed to go out to supper (Raoul says she is to be ready in 2 minutes). Her hair becomes 'bigger' and wilder, too. The change in her appearance is a reference to her descending (voluntarily, I might add - he didn't drag her through that mirror) into the Phantom's dark existence and to her sexual awakening.

Audio problem: Right after Joseph Buquet is killed, Raoul runs and finds Christine. When she says, "Raoul, we're not safe here.", her lips do not move; her mouth is merely agape.

Visible crew/equipment: When Christine and Raoul are riding the horse out of the graveyard, it is obvious that Emmy Rossum has been replaced by a stunt double.

Other: During the gypsy fair, when the young Phantom is hurriedly pulling the bag back over his head, you can see the actor's face from the side, through the bars of the cage. There is no deformity, even though the angle of the shot shows the top right of his face, where the mask is always worn later. Even moreso: his deformity is bumpy, and the side of his face is all baby smooth.

Continuity: In the last scene, Christine pulls the cover off one mirror. The coverings stay like this till the Phantom leaves, when both mirrors are uncovered.

Continuity: After being abducted during the Don Juan performance, Christine changes into the wedding gown and the Phantom places the veil on her head. The veil gets thrown aside by the time Raoul arrives. Between the time Christine leaves and the mob arrives, there is a shot of the mannequin with the veil perfectly positioned on the head (although it is highly unlikely that someone took time to put it back.) When Meg walks through the lair and retrieves the mask, yet another shot of the dummy shows that the veil has disappeared.
