The third and final "X-Men: Days of Future Past" arrived Tuesday night, with about five weeks to go before the release of Fox's latest Marvel film. Accompanied by Led Zeppelin's "Kashmir," the two-and-a-half minute clip reveals more of the time-travel film's structure -- showing Wolverine (Hugh Jackman) and Beast (Nicholas Hoult) gathering mutant help in the "X-Men: First Class" timeline, and Wolverine trying to convince a skeptical Professor X (James McAvoy) that he is, indeed from the future -- along with a heavy focus on Sentinels and a major set-piece involving Magneto and a stadium.

Directed by Bryan Singer and in theaters May 23, "X-Men: Days of Future Past" stars Jackman, Patrick Stewart, Ian McKellan, Halle Berry, Ellen Page, Anna Paquin, Shawn Ashmore, Daniel Cudmore, Booboo Stewart, Fan Bingbing, Adan Canto, McAvoy, Michael Fassbender, Jennifer Lawrence, Hoult, Evan Peters, Peter Dinklage and more.
