Just a little while ago, Matthew Vaughn dropped out of directing X-Men: Days Of Future Past for Twentieth Century Fox. Many fans thought it was kind of odd that he would suddenly step away as director of what will surely be a big budget X-Men movie, after he direct the financial and critical success X-Men: First Class.
Collider claims that the reason he is no longer directing the X-Men sequel is because of the opportunity to direct the next Star Wars movie. With Star Wars Episode 7 set to hit theaters in 2015, it probably would be difficult for him to also direct an X-Men movie being released in summer 2014. Disney CEO Bob Iger did classify Star Wars Episode 7 as being in the early stages of development, so we know Disney is talking to someone, and Matthew Vaughn seems as credible a rumor as anyone else.
