First things first, this movie has some issues. It is set during the Cuban Missile Crisis. That would be around 1962. Wolverine Origins was set during the Three Mile Island accident so that’s around 1979. The beginning of X-Men 3 shows professor X and Magneto visited the Grey household estimating the date to be around 1986. With that established, Havok and Cyclops being brothers is going to be hard to pull off. A 17 year age difference is very improbable, but not impossible. Remember, there is a third brother floating around somewhere.
No one seems to think about the age difference between Cyke and Jean Grey. If he was at least 15 in Origins and she was 13 or 14 in X3, Cyke would have been in his early 20’s by then.
Azazel is Nightcrawler’s father, okay that works. Mystique can hide her age easily enough with her powers and Hank Mccoy is older than the rest as seen in X3. Hank obviously had an image inducer that hid his furry alter ego on the television.
Banshee and Moira fits this time period, I think. Banshee should have been Irish, his history is important to the character, being a cop for Scotland Yard shows his experience.
Emma Frost must have been in her late 30’s to be the same Emma in Origins. UNLESS, she can mask her image like Mastermind.
A lot with b!tch about it, a lot will praise it, but we’ll all see it.
That’s the best I can come up with, What do you guys think?
