what about Cyclops? Didn't they officially cast him yet?
At first I thought, What? Sinister? In First Class as the villain?
That makes no sense. Its like the Wolverine movie, OK we have a origin story about Wolverine, lets add Blob, Gambit, Deadpool, Cyclops, White Queen, and a bunch of other characters that have nothing to do with Wolverine's past.
But, thinking about it more,
Sinister has been alive for a long time, Magneto remembers him in the concentration camps collecting blood.
He has a lot of history with Cyclops, who could be the focus of the movie.
Havoc is being cast too, he too has history with Sinister.
It does sound like a spin off from the Wolverine movie, but they might show the history that comes before that too with young Magneto and young Xavier.
But having Banshee and White Queen?
Even if they do connect it to Weapon X, I can see Sinister weaseling his way into there to experiment on mutants. Anything to get the chance to do that. He worked with the Nazis to do that.
Kevin Bacon? hmm, not sure but I guess.
Still, Sinister might be a cool enemy for First Class.
