Matthew Vaughn Not Directing X-Men: First Class Sequel

Matthew Vaughn has apparently left the X-Men: First Class sequel to film a movie titled The Secret Service instead.  20th Century Fox is eyeing original X-Men director Bryan Singer as a replacement.  The film is expected to be based on the popular comic book story Days of Future Past and scheduled for release summer 2014, so Fox looks to replace Vaughn rather quickly.  More on this story as it develops.
