X-Men: Days Of Future Past - 25 Easter Eggs & References You Must See

15. JFK's Bendy Bullet

It is revealed at the start of the past timeline sequences that Magneto is indisposed having been arrested and imprisoned in a concrete only prison under the pentagon for life. His crime - as revealed in the viral marketing campaign ahead of the film's release - was assassinating JFK, which was apparently proven by the Magic Bullet theory that instantly implicated him. It turns out that Magneto was actually attempting to save JFK, who was assassinated for being a mutant (as Magneto says "he was one of us") and the bullet's strange trajectory was evidence of his attempt, which was foiled by his captors. Initially it was believed that it would be Mystique pulling the trigger as Lee Harvey Oswald, but it is revealed that until 1972 she hasn't killed a single person.
