Continuity mistake: During the Masquerade, there is a close-up of two of the dancers, who sing "But who can name the face?" while standing next to each other, without moving. Next shot, they are several feet apart and the lady is dancing towards where the male dancer is standing. (01:18:50)

Sereenie

Trivia: When Christine removes the Phantom's mask, he pushes her down on the floor. Right after he says 'Curse you,' the camera goes back to her: she is half laughing. (00:45:30)

Sereenie

Revealing mistake: The second time we see the Christine mannequin, we can see it sway from right to left. The swaying can't be due to a draft, since any sort of wind would have made the candles flicker. The moving is due to the fact that Emmy Rossum is the mannequin. They couldn't get a wax figure to so closely resemble her, so Emmy sat very very still (although not still enough!) and played the mannequin herself. (00:46:15)

Sereenie

Visible crew/equipment: During the graveyard swordfight, the Phantom's stuntman sometimes visibly replaces Gerard Butler. He has thin and very arched eyebrows and the mask doesn't fit properly around the nose. He is the same stuntman used when Raoul jumps down the hole after the Masquerade. (01:40:45)

Sereenie

Continuity mistake: When Christine reaches the centre of the stage during her first appearance in Don Juan Triumphant, her arms are at her sides and she holds the basket in her right hand. The next shot, she is holding the basket in front of her, with both hands. (01:48:40)

Sereenie

Audio problem: When Christine and Raoul leave the lair, singing to each other, she turns her head back toward the Phantom as we hear her singing 'each night, each morning,' but we can see she isn't saying anything: her mouth and lips aren't moving. It can't be that the Phantom is remembering the rooftop scene, because you hear the voices echoing in the cave, resonating differently as they move away. This is confirmed by the screenplay (p. 140 of "The Phantom of the Opera Companion"), which states that the Phantom hears them singing in the distance. (02:09:40)

Sereenie

Continuity mistake: At the end of the first part of Don Juan Triumphant, Carlotta throws her right arm towards her back right, holding a fan. In the next shot, her right arm is at her side and her left arm is pointing forward to her left. (01:47:20)

Sereenie

Visible crew/equipment: Just before Raoul jumps down the hole after the Masquerade, Patrick Wilson is obviously replaced by a stuntman who's not even trying to hide his face. He is the same stuntman used for the Phantom in the graveyard swordfight. (01:25:35)

Sereenie

Continuity mistake: In the graveyard, when Christine walks down the main alley, her arms are hanging by her sides, but in the next shot, she is holding her bouquet in front of her hips. (01:36:40)

Sereenie

Continuity mistake: After the the auction, the old Madame Giry bows her head at Raoul. In the following shot, we can see her reflection in Raoul's window, bowing her head once more. Furthermore, Raoul's car leaves before her head is back in the up position. (00:47:50)

Sereenie

Continuity mistake: After Christine removes the Phantom's mask for the first time, he looks at himself in a mirror: his 'bad side' (the right one) shows no sign of deformity. (00:45:30)

Sereenie

Visible crew/equipment: As Raoul's car is leaving the Opera House, a crewmember is reflected in its windshield. (00:48:05)

Sereenie

Other mistake: While running to the rooftop, Christine always leads Raoul. She is the first to get up the stairs, and there's no room for him to pass her without her stopping her frantic pace (which she shows no sign of doing), yet somehow ends up only rushing out the door after Raoul does. (01:06:30)

Sereenie

Continuity mistake: When Christine takes off the Phantom's mask during Don Juan, the appearance of his face suddenly gets drastically CG enhanced. (This occurs AFTER Christine has already removed the mask, as the two screenshots show.) (01:55:10)

Sereenie

Trivia: Christine's attire during her performance of 'Think of Me' for Hannibal is copied from the most famous painting of Emperess Elisabeth of Austria, also known as Sissi.

Sereenie

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.

Sereenie

Factual error: It's impossible to receive a phone call on a Bell Canada public phone, as Jill did. (01:25:10)

Sereenie

Factual error: The masquerade is set on New Year's Eve. We know that because its poster reads "Bal masqué de la Saint-Sylvestre" - St. Sylvester's Day is December 31st and it's common in French to call that day by its saint's name. Firmin (or André) says that it's been "Three months of relief, of delight, of Elysian peace." This means that the events on the opera house's roof took place in late September or early October at most. When Paris gets snow, it's usually in January, the coldest month according to Météo France. With average temperatures of 15 degrees in October, and higher in September, having a good centimetre or two of snow on the rooftop at that time of year is quite implausible.

Sereenie

Continuity mistake: Bridget comes back from the Law Society dinner late at night; it is dark outside. Yet when she comes back home and passes by the stained glass window in her apartment, plenty of light is coming through it. (This shot has been cut from the DVD release.)

Sereenie

Deliberate mistake: When Bridget lands in the pigsty, the crew members are outside the sty, around three metres from her. Yet when we see the repeated shot of her buttocks in the studio, it is filmed as if she had landed on the camera or very close to it, and at an angle that would preclude it being a close zoom.
