An enterprising Tumblr user discovered that the book also contains 17 new images from the upcoming X-Men: Days of Future Past as well. Check out these behind-the-scenes photos featuring director Bryan Singer, Patrick Stewart, Ian McKellen, Ellen Page, Nicholas Hoult, Hugh Jackman and Michael Fassbender working hard on the set.
