X-Men: The Last Stand (2006)
X-Men: The Last Stand (also known as X-Men 3 or X3) is a 2006 British-American superhero film, based on the X-Men superhero team introduced in Marvel Comics. The film, distributed by 20th Century Fox, is the third installment in the X-Men film series. It was directed by Brett Ratner, written by Simon Kinberg and Zak Penn, and features an ensemble cast, including Hugh Jackman, Halle Berry, Patrick Stewart, Ian McKellen, Anna Paquin and Famke Janssen. The film's script is loosely based on two X-Men comic book story arcs: "The Dark Phoenix Saga" by writer Chris Claremont and artist John Byrne, and "Gifted" by writer Joss Whedon and artist John Cassaday, with a plot that revolves around a "mutant cure" that causes serious repercussions among mutants and humans, and on the resurrection of Jean Grey.
