Two clips from Days of Future Past have Xavier, Magneto, Mystique, and Trask
Say so long to trailers and TV spots, now FOX is releasing actual clips from X-Men: Days of Future Past. Two have been released that feature Xavier and Magneto with the second having Mystique face Bolivar Trask.
If you want to walk into Days of Future Past with as little information as possible I would recommend skipping the first clip and instead watch Jennifer Lawrence be totally kick-ass in the second clip.
X-Men: Days of Future Past releases May 23rd.
