The film will be based on the comic book storyline “Days of Future Past,” which ran in Uncanny X-Men #141 and 142 back in 1981 during Chris Claremont and John Byrne’s run and introduced the idea of an alternate future for Marvel’s mutants that grew out of the Brotherhood of Evil Mutants killing an important senator, leading to a future where all mutants are hunted by Sentinels.
