It's been a little quiet for X-Men: Days of Future Past since the first teaser was released last October, but according to the film's Instagram account that will change tomorrow. Before Mutant Monday begins and fans are treated to Empire's "exclusive reveal," the account uploaded a quick video with new footage. Perhaps an extended trailer is in the cards for tomorrow? Until then, watch this clip a couple hundred times for clues, including someone (Wolverine?) sinking underwater, lots of past and present Magneto, and a blink-and-you'll-miss-it shot of Evan Peters as Quicksilver. Check back here tomorrow for an update on the reveal.
