The teaser images seamlessly blend the faces of Patrick Stewart & James McAvoy and Ian McKellen & Michael Fassbender, representing future and past versions of Professor Xavier and Magneto, as well as the central time-traveling elements of elements of the sequel.
The film is based on the 1982 Marvel Comics storyline by Chris Claremont and John Byrne in which the X-Men’s failure to prevent the assassination of a U.S. senator by the Brotherhood of Evil Mutants results in the creation of a dystopian alternate timeline. There, the giant, robotic Sentinels have become the de facto rulers of the the United States, where mutants are hunted down and placed in internment camps. In that future, Kitty Pryde sends her mind back to possess the body of her younger self in an attempt to warn the X-Men and stop the future from coming about. A report that surfaced last week suggests some key changes have been made for the movie.
