Resorting once again to social media, director Bryan Singer posted a Vine video this morning that reveals the addition of Bishop and Warpath to the sprawling cast of characters in "X-Men: Days of Future Past."

In the video, below, the camera pans a semicircle of personalized chairs, with quick cuts of those for Logan, Xavier, Magneto, Storm, Bishop, Kitty Pryde, Bobby "Iceman" Drake, Peter "Colossus" Rasputin, Blink and James "Warpath" Proudstar.

That would seem to confirm speculation that "The Intouchables" star Omar Sy will play the time-traveling antihero Bishop, and point to "The Twilight Saga" actor Booboo Stewart in the role of Warpath, the longtime member of Marvel's X-Force (his older brother Thunderbird was a short-lived X-Man). Fan Bingbing has been cast as the teleporter Blink.

"X-Men: Days of Future Past" takes its name from the classic 1981 Marvel comics story by Chris Claremont and John Byrne that depicts a timeline created by the X-Men's failure to prevent the Brotherhood of Evil Mutants from assassinating a U.S. senator. In that alternate future, the giant robotic Sentinels have become the de facto rulers of the United States, where mutants are hunted down and placed in internment camps.

Opening July 18, 2014, the film also stars James McAvoy, Michael Fassbender, Nicholas Hoult, Jennifer Lawrence, Hugh Jackman, Ian McKellen, Patrick Stewart, Halle Berry, Anna Paquin, Ellen Page, Shawn Ashmore, Peter Dinklage, Daniel Cudmore and Adan Canto.
