Bryan Singer gave us another teaser for X-Men: Days of Future Past as the director posted an image of a Charles Xavier document for the CIA.
There was no accompanying text with the tweet, but we can recall the CIA's involvement in X-Men: First Class, which suggests the secretive organization will have some role in Singer's movie.
It's quite possible this might even lead to development of the rumored Sentinels for the movie and Peter Dinklage's character down the line.
Also suggests James McAvoy to be involved with the CIA as well.
X-Men: Days of Future Past has a July 14, 2014 release date starring Jennifer Lawrence, James McAvoy, Michael Fassbender, Nicholas Hoult, Anna Paquin, Ellen Page, ShawnAshmore, with Hugh Jackman reprising as Wolverine, and returning cast members Patrick Stewart and Ian McKellan.
