Corrected entry: The events at the end of this film are supposed to have happened at Three Mile Island, which occurred in 1979. Yet in X-Men, Professor X says it's been "fifteen years since your memory loss". X-Men takes place in the "near future" and was released in 2000.

Correction: Perhaps because of Wolverines healing factor. Professor X could not get an exact date. Also, we dont know what else Wolverine has been through before he met the Professor.
