Bryan Singer, the director of the first two X-Men movies left early in the production of the movie to direct the movie "Superman Returns". Screenwriters Dan Harris and Michael Dougherty and composer John Ottman left with him. Singer has said that, at the time he left, they had partially written a story for the movie which would have been only about Jean Grey's resurrection. The story would also have a new villain Emma Frost, played by Sigourney Weaver.
