I really can't wait till Day of Future Past is released and of course there have been no official cast listings yet, but we can be pretty certain that Jennifer Lawrence will return as Mystique, Michael Fassbender as Magneto and James McAvoy as Professor X.
But the good thing about Days of Future past is that it's a time travelling storyline and it is likely that Patrick Stewart will meet McAvoy and that Ian McClennen will meet Fassbender, I would love for this to happen, but I would love to know which X-Men you want to see in this movie and who you really want to play them. I'm still drawing out a cast list mentally of who I want to be who and I think your opinions would help me a lot.
One actor and character really connect together very well for me is Emily VanCamp as Magik. Let me know what you think and please share your cast lists.
