It looks like past Professor X is going into
Days Of Future Past
with a serious sad face.
Not only has he grown a
beard of sorrow
, but his older self can't stop going on about how upset he used to be (even when he's talking to himself).
Basically, he was looking for a job (leader of a mutant super-team), he found a job (by creating an arch-nemesis) and heaven knows he's miserable now (still, he's saving money on razors, which is a reason to cheer up a bit).
For further insight, just watch our recent video interviews with James McAvoy, who raved about playing Prof X, and in the Social Media interview below also revealed quite how 'bad-ass' his Professor X is going to be in DOFP.
