X-Men: Days of Future Past: 25 Empire Covers showcase the cast, mutants, and sentinels

With just a couple of months left until the movie hits theaters in time for the summer, 20th Century Fox and Marvel have paired with Empire Magazine to present not 1, 2, or 3 covers promoting Bryan Singer's next X-Men film... But 25 different cover photos of the different characters, mutants, and even The Sentinels appearing in "X-Men; Days of Future Past"!

Above is one of the covers, and it's the copy featuring one of Trask Industries elite Sentinel units... Which will no doubt play their part in "protecting humanity" from the "mutant threat" one way or the other. The other covers are expected to be revealed as the hours roll by.

X-Men: Days of Future Past hits theaters on May 23, 2014.

X-Men: Days of Future Past: Viral Marketing Campaign begins, shows Sentinels and Peter Dinklage as Bolivar Trask

If you've seen "The Wolverine" in theaters and stayed until the mid-credits sequence, there'd be a special scene playing that connects the James Mangold movie directly into next year's most anticipated X-Men sequel, namely X-Men: Days of Future Past. Reuniting the cast from previous X-Men films with that of the 2011 prequel hit X-Men: First Class, the movie will be directed by X-Men and X2 film guru Bryan Singer, returning once again to helm the mutants in their finest hour.

Not one to keep the surprises and build-up at bay, Singer has constantly tweeted surprises in store for the next film, including some behind-the-scenes photos every now and then of cast members suiting up as your favorite men and women from the X-Men film universe. However, the newest viral marketing campaign heats things up by showing off more from Trask Industries and their mutant hunting robot drone army that are the Sentinels... Featuring "Game of Thrones" star and Tyrion Lannister himself Peter Dinklage, who plays Bolivar Trask in the film!
