Continuity mistake: When the chosen one for the Thieves Guild is called forward to present their tithe, the chosen one for the Assassins Guild can still be seen kneeling before the External. In the next shot when the chosen one for the Thieves is shown arriving on the scene, the chosen one for the Assassins is suddenly back to standing among the other members of his guild. In the next shot, the chosen one for the Assassins is back to kneeling before the External. (00:06:00)
Continuity mistake: When the chosen one for the Thieves Guild tries to present their tithe to the External, he is shown walking right up to the tree stump where he was to have placed the tithe. When the shot changes, he is still walking forward, and therefore should've bumped into the stump. He is saying a line of dialogue as he is walking forward, so it can't be considered an action shown from a different angle. (00:06:15)
Continuity mistake: When the chosen one for the Guild of Thieves drops his tithe box, it lands on the inside of his right foot. When the shot changes, the box is suddenly equidistant between his feet. A couple of shots later, the box has moved away from him, resting next to the tree stump. (00:06:17)
Continuity mistake: When Bella Donna is being selected as the chosen one for the Guild of Assassins, she is flanked by three of her guild members. When the shot changes, the three guild members have disappeared. (00:06:49)
Continuity mistake: When the External selects Bobby to be the chosen one for the Guild of Thieves, she turns his jacket red and his gloves gray and fingerless. When he is shown again a few shots later, his jacket is now green, and his gloves are brown, with only the thumbs being fingerless. (00:06:53)
Continuity mistake: When Wolverine enters the infirmary, Cyclops is resting his right hand on his lower abdomen area with his fingers extended. When the shot changes, his hand is a closed fist and has moved closer to his chest. (00:07:37)

Continuity mistake: After Jean Grey, Rogue and Wolverine locate Gambit's mini-jet, they land the Blackbird behind a row of plants. When they emerge from the Blackbird, the plants have disappeared. (00:08:55)
Continuity mistake: When Wolverine runs up to Gambit's mini-jet, he puts a considerable amount of distance between himself and Jean Grey, and nearly makes it all the way to the jet and Rogue before the shot changes. When the shot does change, he is suddenly several feet back from where he just was, and Jean Grey is now right behind him. (00:09:01)
Continuity mistake: In the first establishing shot of the Assassins Guild's mansion, there is a stairway leading up to the front door. In the establishing shot of the mansion in the scene where Gambit is in Bella Donna's bedroom, the stairway is missing, and consequently the mansion's porch area isn't as high off the ground. (00:09:20 - 00:13:20)
Continuity mistake: The two assassins standing guard outside the Assassins Guild's mansion have swapped sides when they let Gambit in the front door. (00:09:25)
Continuity mistake: When Gambit first walks into Bobby's cell, Bobby is sitting in a chair up against the back wall. A few shots later, Bobby is sitting in the center of the cell. (00:09:55)
Continuity mistake: The cell that Bobby was held captive in is noticeably smaller after he is set free. (00:09:55 - 00:11:40)
Continuity mistake: When Gambit is saying "You got me in the guild, Bobby," you can see on the wall across the hall that there is a switch that is the same red color as the wall. A few shots later, the switch is now gray. (00:10:18)
Continuity mistake: Bella Donna's engagement/wedding ring from Gambit doesn't appear on her finger until she mentions that she still wears it. (00:10:55)
Continuity mistake: When Bobby starts walking out of his cell, Gambit has his back to him. When the shot changes, Gambit is suddenly facing him. (00:11:15)
Continuity mistake: After Bobby is set free, Gambit, Bella Donna and her henchman remain in Bobby's cell. When Bella Donna begins torturing Gambit, the two of them are suddenly alone in the cell. (00:11:20)
Continuity mistake: When Bobby and Pierre enter the basement of the Thieves Guild's mansion, Bobby is on the left, and Pierre is on the right. When the shot changes, they have swapped places. (00:12:43)
Continuity mistake: When Gambit is looking at himself in the mirror while wearing a tuxedo, you can see in his reflection that he is barehanded. In the next shot when he removes the tuxedo, he is wearing his usual black gloves. Also, the rose on the tuxedo goes from being on his right side (reflection's left) to being on his left side just before he removes the tuxedo. (00:13:15)
