Audio problem: When the Phantom takes Christine down to his lair the second time, in the shot where the camera is behind his neck and facing Christine, you can see that the movements of his jaw are out of synch with the words he's supposed to be singing.

Audio problem: In the opening song of Don Juan, Carlotta obviously cuts early, although her voice is still heard hitting the high (and obnoxious) note. (Timecode)

Continuity: When the young phantom is murdering the carnival man, young Mme Giry walks though the gap in the tent, and turns so all you can see of her is her eye and the side of her face. In the next shot of her, her whole body is inside the tent.

Continuity: 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. (Timecode) Submitted by Sereenie

Continuity: When the Phantom is singing and close-ups are done on his face, you can see his right eyebrow peeking out from under the mask. But we see later, when he is shown without his mask, that he has no eyebrow at all on that side as a result of his deformity.

Audio problem: During Christine's lines in her first scene of the film, her lips don't match what she's saying. Her lines must be added during post-production.

Audio problem: Several times during "Masquerade", starting with the very first shot of the chorus singing, the audio does not at all match their lip synchs. (Timecode)

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.

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. (Timecode) Submitted by Sereenie

Continuity: At the very beginning of the movie when Andre and Firmin first arrive in their coach in front of the opera house, you can see one footman (wearing red) running to meet them from some distance to escort them inside. The camera angle changes and now, that fotman turned into two, standing and even waiting at the coach. (Timecode)

Revealing: When the Phantom first appears in "Don Juan," he is wearing his shorter full face mask showing his neatly trimmed sideburns. This continues until he and Christine reach the top catwalk when the neatly trimmed sideburns have been replaced by pretend sideburns and rubber prosthetics necessary for the removal of the Phantom's mask. The prosthetics also shine differently in the stage lights whilst the Phantom is wearing them. Most obviously as he arrives at the top of the stairs of the catwalk.

Continuity: During the scene where Meg is looking for Christine backstage, we see her pass Firmin and Andre. Behind her Raoul approaches the managers and they turn to greet him. In the next shot they are turned round flirting with the chorus girls and Raoul is nowhere to be seen. (Timecode)

Continuity: On the Opera House's rooftop, the lining of the Phantom's cape goes from light-coloured to black before and after he jumps on the statue. It has nothing to do with lighting, and his waistshirt proves it: much darker than the cape's original lining, it makes it obvious the cape's turned dark since the waistshirt looks paler against it.

Continuity: In the gypsy fair scene the Phantom has a dirty back. In the next scene when he's running away with the Dancing Mistress to go under the Opera House, his back is clean.

Continuity: When old Raoul is watching the young couple outside the Swarovski shop his eye turns brown as we move back in time, but young Raoul's eyes are blue.

Continuity: 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. (Timecode) Submitted by Sereenie

Continuity: 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. (Timecode) Submitted by Sereenie

Continuity: 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. (Timecode) Submitted by Sereenie

Audio problem: Right after Firmin says "It would appear they've met before." Andre replies "Yes." However, his mouth and the words don't match up. (Timecode)

Revealing: In a scene soon after "Think of Me," it shows a large crowd of actors, crew, etc. celebrating backstage. In one far-away shot, you can pick out Andre and Firmin in the center flirting with two of the women. Andre sticks his cigar in a woman's mouth, and she blows a puff of smoke. A few shots later, it shows the same thing, but much closer up and from the side. (Timecode)
