X-Men: The Last Stan is a 2006 superhero film and the third in the X-Men series. It is directed by Brett Ratner, who took over when Bryan Singer dropped out to direct Superman Returns. The movie revolves around a "mutant cure" that causes serious repercussions among mutants and humans, and on the mysterious resurrection of Jean Grey, who appeared to have died in X2. The film is loosely based on two X-Men comic book story arcs: writer Chris Claremont's and artist John Byrne's "Dark Phoenix Saga" in The Uncanny X-Men and writer Joss Whedon's and artist John Cassaday's six-issue "Gifted" arc in Astonishing X-Men.
