X-Men:-Days-of-Future-Past-Professor-XThe first trailer for one of this summer’s mammoth blockbuster, X-Men: Days of Future Past, launched last year, giving an undeniably epic first look at director Bryan Singer’s return to the franchise.

Singer has taken to Twitter to announce that something ‘BIG’ will be released this coming Monday, teasing a great little preview ahead of whatever we have coming. Could it be the second trailer? (Quite probably.)

The ultimate X-Men ensemble fights a war for the survival of the species across two time periods in X-MEN: DAYS OF FUTURE PAST. The beloved characters from the original “X-Men” film trilogy join forces with their younger selves from “X-Men: First Class,” in an epic battle that must change the past – to save our future.

Reuniting the casts of the original X-Men movies with that of X-Men: First Class, the film boasts one of the best casts of the year with James McAvoy, Michael Fassbender, Hugh Jackman, Patrick Stewart, Ian McKellen, Jennifer Lawrence, Nicholas Hoult, Shawn Ashmore, Ellen Page, Peter Dinklage, Omar Sy, and Halle Berry, with Anna Paquin’s appearance remaining something of a question mark at the moment.

Singer directs from a script by Simon Kinberg (Sherlock Holmes), based on the original arc, Days of Future Past, by Chris Claremont, John Byrne, and Terry Austin.

X-Men: Days of Future Past will be released on 22nd May in the UK, landing a day later on May 23rd in the US. Whilst we await Monday’s big reveal, here’s the new footage to help tie you over. Enjoy.
