Continuity mistake: When young Magneto is struggling with the guards at the concentration camp, the father's star switches from one side of his chest to the other. (00:01:46)
Continuity mistake: Just after the soldier hits the young Magneto with his gun, the guy on the left is holding him and he turns away looking at the ground (probably so he knows where to fall). Yet in the following shot, the boy is looking up on top of the guy who is facing up. (00:03:35)
Continuity mistake: When Rogue is seen for the first time, her hand is moving up photographs on the wall, and if you look closely there are some kind of red poppies when she reaches the end, yet when it cuts to another shot a bit further away, her finger is a lot further down the wall from the red poppy/flower. (00:04:15)
Continuity mistake: At the start when Rogue walks into the bar, when she walks towards the cage, note all the things around her from the camera's perspective (which is from behind her): the wooden plank in front of her which she walks around, and the burning can to the left of the screen. When the camera cuts to the front, the wooden plank is not there and neither is the burning can (now to the right of the screen). (00:09:35)
Continuity mistake: When Rogue sits at the bar, as the bartender cleans a cup, a metal ashtray appears beside Rogues glass of water between shots. (00:11:20)
Continuity mistake: After the guy comes at Wolverine with a knife, Wolverine holds him against a wooden post. His jacket is off his shoulders after being pushed against the post, but when Wolverine slices the shotgun in half the jacket is back on his shoulders. (00:12:50)
Continuity mistake: In his truck, Wolverine is smoking a cigar while the window is rolled up. But when he stops after hearing a noise, the window is now rolled down. Then the window is a quarter way up as he gets out of his truck. (00:14:45)
Continuity mistake: When Wolverine crashes into the tree knocked over by Sabertooth, notice that the entire front of the truck gets completely folded up and the windshield breaks into a thousand pieces. In the next frame, Wolverine gets thrown through the unbroken windshield and the front of the truck is practically undamaged... (00:18:05)
Continuity mistake: At the beginning, when Storm and Cyclops are standing behind Sabretooth, the camera cuts to Cyclops. He raises his right hand to shoot his red beam at Sabretooth, but when the shot cuts to a wider shot he has his right hand by his side. (00:19:25)
Continuity mistake: The direction Magnetos helmet faces as it sits on his desk in his lair constantly changes between shots. (00:20:20 - 00:21:15)
Continuity mistake: When Wolverine has just walked into Xavier's office for the first time, a girl picks up her book then runs towards Wolverine. Her left hand is on her bag, but in the following shot when Wolverine looks over his shoulder, her left hand is now on the left strap of the bag. (00:24:10)
Continuity mistake: Close to the beginning of the film when Rogue is in a classroom with other students, she has two books in front of her, yet in a few shots later the books change position on the table. (00:26:40)
Continuity mistake: When Senator Kelly gets out of his limo and waves to the crowd, in the first shot, he moves to stand in front of the door, yet in the following shot he is still behind the door. (00:28:45)
Continuity mistake: When Logan is in bed in Xavier's mansion, Rogue walks in and tries to wake him. When Jean says, "Scott, grab a pillow," Rogue is still facing in Logan's direction, then it cuts and she is now facing Storm. (00:38:40)
Continuity mistake: Close to the middle when Senator Kelly hangs over the edge of the cliff face, Magneto pulls away the metal bars and crosses his hands/fingers twice. (00:40:30)
Continuity mistake: When Magneto discovers Senator Kelly has got out of his barred window, he then leaves the room, out of an opening he made in the barred door. As he leaves, between three shots the amount of bars that are bent on either side of the opening actually differs. (00:41:20)
Continuity mistake: Just after Sabertooth has dropped the Senator into the water, the mutated Senator pops out of the water. In the first shot, he is facing the boy, but in the next shot he has his back to the boy, then facing the boy again. Also, when he pops out the water he is only a few feet away from the boy's yellow boat, yet in another shot he is much farther from the boat. (00:41:30)
Continuity mistake: When Storm and Cyclops are in the train station, and Toad whips Cyclops goggles off, he punches a hole through the ceiling of the train station behind him, yet the hole changes from behind him to above Storm between shots. (00:50:30)
Continuity mistake: When Cyclops and Storm are in the train station, Storm is held up by Sabretooth, Cyclops spots this and starts to walk over to help. He stretches his arms out between a lot of people to push two people out the way, yet when the shot changes to Toad's POV all the people around him are at least two to three feet away from him. (00:50:30)
Continuity mistake: In the Statue of Liberty scene just after Wolverine, Storm Cyclops and Jean go through the metal detectors, they walk off and watch in the background, you can see Wolverine walk past Cyclops yet in the following shot he is walking past again. (01:09:25)
Chosen answer: You are working under the assumption that Mystique would not believe this either. However, with Magneto in prison and no sign of the senator she could happily take on his identity. Also, even if Kelly was alive, after she gave a press statement backing mutants, it would be unlikely that a politician would change his mind so suddenly again and he would therefore not come clean that it was not him.
