Director Bryan Singer has confirmed that X-Men: First Class star Lucas Till is returning as Alex Summers/Havok in X-Men: Days of Future Past with a photo from the Montreal set. Havok appears in his Army fatigues, with Bryan Singer pulling a quote from President John F. Kennedy to make his announcement. We know that Richard Nixon is a part of this story from a photo released last month. Does this cryptic quote mean JFK is included in the narrative as well? The story is based on Chris Claremont and John Byrne's comic book arc set in an alternate future where all mutants are hunted down by Sentinels after the death of a Senator at the hands of the Brotherhood of Evil Mutants.
