Not too far into the movie Magik 'Illyana' shows Mirage 'Dani' around the school and grounds, there's a fountain in front of the main entrance where Magik has stashed some spray paint, she proceeds to spray a bit of graffiti onto the base of the fountain. Throughout the movie whenever you get a shot from the same perspective, the graffiti has disappeared and then it returns, then it's gone again.
Several of the cast members' accents change during the film.
The amount of blood from Dani's nose changes from shot to shot.
When Rahne and Dani knock the vent cover off while leaving the vents, you see it fall and hear the bang. Then in the wider shot, the vent cover is gone.
Characters are kept at the facility behind a force field so they cannot escape. Illyana's mutant power is teleportation. She has to go to Limbo first, then she can teleport anywhere/when she wants. She is shown teleporting during the battle. So her powers aren't blocked. She could leave the facility at any time, and she would be able to teleport others with her.
In a deleted scene, Illyana talks to Bobby, where it is established that she is incapable of teleporting out of the force field.

The wood behind the clock is broken by Dani. Later in the movie, it is shown undamaged. However, at the end of the movie, it is shown damaged again. When the clock is first shown, after Dani kicked through the face, it may have been a different side of the clock tower that was shown.
When Dani (Blu Hunt)is unconscious while the Demon Bear is rampaging,she is pictured running around in the snow barefoot,which should be impossible;however,it is easily explained by the fact that she is obviously not in the real world but locked in an imaginary dreamscape.
