If I am to understand things correctly all of the X-Men movies we've had so-far take place "in the same universe" which is fine and good but between the different directors and the 13 year time span between X-Men and The Wolverine the consistencies seem... muddy. For all intents and purposes it seems that end of "Origins: Wolverine" take place in 1979. I say that as I'm guessing the incident at the Three Mile Island nuclear power plant was "covered up" as being the partial meltdown that happened there in that year. Granted, that's pure speculation but the time of the movie is hard to pin down as it seems not too much attention was paid to trying to establish a time-period. So in "X-Men" Professor-X suggests that Wolverine has been drifting on his own for "15 years." We'll ignore that the movie claims to take place in "the not too distant future" (or by that it's speaking in a matter of days, weeks or maybe months.) But Wolverine has been drifting on his own for probably closer to 20 years. (TMI incident: 1979, X-Men: 2000.) In X-Men Professor-X says he was 17 when he met Magneto but in "First Class" Charles Xavier is in his early 20s/in college when he meets Magneto and, of course, the big one being the movie seems to take place over the course of months maybe at the end of which Xavier ends up crippled and he and Magneto gone their different ways. We see a teenage Scott Summers in Origins (again, 1979) but he certainly doesn't seem to be man pushing 40 in X-Men and, well, we could go on and on. You know, maybe this movie series needs a huge reboot in order to make consistency here.
