One of the big fan concerns about X-Men: Days Of Future past has been that the Sentinels might appear too small or human size. The Sentinels tower over the X-Men in the comic books, and fans want to see that same large size in the movie. Well, X-men: Days Of Future Past director Bryan Singer has just tweeted a new photo, which should put any fan concerns at rest. Singer tweeted a photo of himself standing next to a Sentinel, and it really shows that the Sentinels will tower over normal-sized humans and X-Men in the X-men Days of Future Past. According to the Trask Industries viral website, the Sentinels are 18 feet tall with a weight of 4,880 lbs. X-Men: Days Of Future Past stars James McAvoy, Michael Fassbender, Patrick Stewart, Ian McKellen, Hugh Jackman, Jennifer Lawrence, Nicholas Hoult, Ellen Page, Halle Berry, Peter Dinklage, Anna Paquin and Shawn Ashmore. X-Men: Days Of Future Past is scheduled to be released in movie theaters on May 23, 2014.
