Re: X-men Movie Timeline
We can even more precise with some of the ages, at least according to the cast credits.
The actor who played young Xavier in 1944 is credited as "Charles Xavier (12 Years)" and the girl who was young Mystique is credited as "Young Raven (10 yrs)."
Based on that information, Xavier was 30 at the end of First Class and Mystique was 28, and Xavier was 62 in 1994 and Mystique was 60 (though her cells age at half the normal rate).
Jurassic World 4/10, Star Wars: TFA 5/10, Batman v Superman 6/10, The Jungle Book 8/10, Deadpool 8/10, X-Men: Days of Future Past 9/10
