Audio problem: Right before the jet fight, Logan asks Storm "How far are we?" He says this line in his natural Australian accent. Submitted by Piemanmoo

Continuity: When Mystique (as Dr. Jean Grey) tries making out with Wolverine, we see that the scars that Wolverine made in the first film are vertically across her stomach. But in X-Men, when Wolverine stabs Mystique with his claws, the marks (which later become scars) are horizontally across her stomach.

Continuity: When Jean and Storm first meet Nightcrawler and hold him mid-air, you can see his coat fall down ("up" by his view) when you're looking at him from their point of view, but when the camera is on the other side, the coat is sticking to him so you can see the two of them.

Continuity: At the beginning of the film in the museum scene when we first see Pyro and Iceman, there is a man with a green sweater that is sitting behind Iceman. In the next shot he's sitting beside him, then is behind him in the next shot. You can also that in one shot he is looking in Pyro's direction but in the next shot, he isn't.

Other: During a closeup in her fight with Wolverine, Kelly Hu's contact is not on straight, making her pupil not the center of her iris.

Continuity: This is on the DVD. When Storm and Nightcrawler rescue the children Storm shouts "Jubilee" but the subtitles have her name as being "Julie".

Continuity: In the scene where Stryker is walking through the tunnel in Alkali Lake, a drop of water drips onto his glasses thereby alerting him to the breaking of the dam. He examines the drop on his lens, but when he puts his glasses back on, the lens is dry.

Continuity: When Wolverine returns home to the Xavier mansion, Rogue greets him, they talk, and when Jean arrives Rogue leaves them alone. In one shot Rogue's hair is over her left shoulder running down her chest, but in the following shot all of her hair is at the back. Submitted by The-Immortal

Continuity: When the SWAT team raid Xavier's mansion, a SWAT member walks into the kitchen where Bobby is but Wolverine grabs him which causes him to fire. The napkins on the table get shot at, then fall onto Bobby who is kneeling down behind the kitchen table, but in the following shot they are falling down again. Submitted by The-Immortal

Continuity: Near the start Logan is inside Cerebro with Xavier and Xavier turns to talk to him. The chair he's sitting in doesn't go any higher than the top of his back, yet a few shots later, the chair is now above his neck. Submitted by The-Immortal

Visible crew/equipment: When Magneto and Xavier are speaking inside the plastic prison , look to the right of Xavier's head when Magneto says something about "failure with Stryker's son". There is a partial view of a piece of some kind of equipment moving around lightly reflected in the glass. It's definitely not one of the actors by it's shape.

Revealing: In the beginning of the movie when Wolverine puts the cigar out in his hand, you can see the mark of a wedding ring on his ring finger (Hugh Jackman is married). Even if Wolverine got married during the "blurred" bit of his memory so doesn't remember it (tenuous at best), his healing ability would have removed any ring mark. Either way it just doesn't belong.

Revealing: In the part where Mystique (as Grace) and the guard are in the bathroom, right after the guard drinks the rest of the beer and passes out, Mystique turns him over and you can see the guard move his right leg to steady himself even though he is suppose to be knocked out.

Continuity: In the scene where Wolverine is talking to Stryker in the mansion corridor, Bobby creates an ice wall between them, including the wall. Shortly afterwards when they leave and Bobby takes his hand away, the wall suddenly has no frost on it at all.

Continuity: When Magneto is reversing Cerebro, he is floating and turning clockwise. Just as he passes the door there is a cut and suddenly he is back facing Professor X as he comes back down.

Continuity: When Wolverine is tramping through the snow to Alkali Lake, you get a long shot of him looking at a wolf with the sides of his hair are styled so they're sticking up at least three inches. After he goes through the gate, his hair is totally flat.

Continuity: During the mansion invasion scene, Wolverine jumps from the balcony level. He drops onto one knee, and stabs two soldiers with his claws. He then stands up and throws them off. In the shot from behind once he's thrown them he's still part crouching, but in the very next shot from the front, he's fully upright.

Continuity: In the scene with Wolverine and Bobby at the mansion when Wolverine can't sleep, when he hands Bobby the soda bottle the contents are almost full but when bobby blows on the bottle and hands it back to Wolverine the contents are at the bottom of the bottle neck. Then when Wolverine drinks the Dr Pepper, the bottle is full again.

Continuity: When Cyclops encounters Lady Deathstrike at Magneto's prison and knocks her down with his optic blast, watch her eyes as she's getting up from the ground. Instead of the greyish white they should be while under the control of the serum, they're a rather nice looking shade of blue. When it shows her standing, they are white/grey again.

Revealing: In the scene where the cat licks Wolverine's claw, if you look closely you can see a shiny drop of clear liquid at the end of the claw, probably something to make the cat want to taste it.
