Twentieth Century Fox owns the right to the character played by James McAvoy, and previously by Patrick Stewart. “The movie studio definitely controls that story and those characters and there was a negotiation that had to go on,” Hawley explained. “Going into this third story, that conversation began to be had at the highest levels, because I can’t finish the story unless I can do it.” Hawley says the studio let him do what he wanted to do with the character.
