The synopsis of the movie is the following : When a cure is found to treat mutations, lines are drawn amongst the X-Men, led by Professor Charles Xavier (Stewart), and the Brotherhood, a band of powerful mutants organized under Xavier's former ally, Magneto (McKellen)
For this time it is not Bryan Singer who is the director of the new X-Men movie.
Trivia : for one of the scenes, a 2,500 foot replica of the Golden Gate Bridge was built

Personnally I love X-Men movies because of all the action scenes in it and of all the different kind of characters and mutants. What about you ?
