This question already has an answer here:
I think there's something wrong in the x-men movies..
In X-men : First class, Charles Xavier is paralysed and loses control of his legs even before he starts the school for gifted youngsters.
In X-men origins : wolverine, at the end of the movie, he is seen walking towards young scott and talking to him via his mind.
then, in X-men:The Last Stand, it flashes back 20 years, and you see the grown up Xavier and Magneto, friends, talking to a young Jean Gray.
This is a total contradiction right ?
