Re: Why the 1970's?
Yeah and if they really wanted to make more films set in the past, why bring back the original cast? They could easily make another film with just the cast of First Class and introduce the younger version of Storm, Cyclops and Jean Grey. But they didn't go with that and completely blindsided us with the return of the original cast. They know they aren't gonna earn more money with another First Class movie so they brought back the cast that really appealed to the general audience. I think after DOFP, they will be done with the past period and just move on to the future.
