"Every other actor who’s ever put on a superhero uniform will be in it," he said. "There’s an element of time travel and, naturally, it will be action-packed."
Scheduled for release on July 18, 2014, X-Men: Days of Future Past features a script by Simon Kinberg and is said to be inspired Chris Claremont and John Byrne's comic book storyline that ran in "Uncanny X-Men" #141 and 142 back in 1981. "Days of Future Past" introduced the idea of an alternate future for Marvel's mutants that grew out of the Brotherhood of Evil Mutants killing an important senator, leading to a future where all mutants are hunted by Sentinels.
Already confirmed to appear in addition to Jackman are Ian McKellen, Patrick Stewart, James McAvoy, Jennifer Lawrence, Michael Fassbender and Nicholas Hoult, but expect that list to expand in the very near future.
Jackman, who has appeared in every X-Men film to date, will next reprise his role as Logan in James Mangold's The Wolverine, hitting theaters July 26.
