Continuity mistake: After Carmella Unuscione releases Wolverine and Rogue from her psionic grasp, Wolverine's face is colored blue. (00:15:00)
Continuity mistake: The security footage of Cortez betraying Magneto is slightly different than the event itself. Cortez stated that Magneto would serve the mutant cause better as a martyr and then jettisoned his chambers into space. The security footage somehow has a shot of Magneto's chambers being jettisoned from a long distance with Cortez's martyr comment voiced over. (00:14:40)
Continuity mistake: In the flashback during Magneto's memorial, when the Nazis are approaching his home it says "Lehnsherr" on the door. After they kick the door open, the writing on the door has disappeared and either a hatch or a small window has appeared on the door from nowhere. (00:06:20)
Continuity mistake: When Fabian Cortez is scapegoating Gambit in front of the mob, he grabs him by the blue clothing that lines the body armor on his chest. When he says to Gambit "Mark my words X-Man..." the blue clothing is now the same brown color as Gambit's trenchcoat. (00:05:20)
Continuity mistake: When Rogue is asking about Gambit's whereabouts, she along with Beast and Xavier are close to the front of the shuttle. When the shot changes, the three of them as well as one of the astronauts are suddenly further back in the shuttle (note the doorway). (00:04:25)
