The 3rd official trailer for "X-Men: Days of Future Past" spells out what to expect for the live-action feature film, with the storyline adapted from the graphic novel storyline of the same name. No worries if you missed reading it tho, this trailer will get you on track ~ heh.
As well I really appreciate the new(ly) seen images/sequences, and not just a wholesale rehash of earlier trailers, IMHO.
