'X-Men: Days of Future Past' already has an all-star cast, complete with both veteran and newbie 'X-Men' movie ensembles. Most of our favorite mutants are set to be featured, but now some new ones we haven't seen in the live-action big screen sense are coming our way. Say hello to Bishop and Warpath.

As with most of our 'X-Men' movie news, this latest character development comes from director Bryan Singer's Twitter, which recently released a Vine compilation showing off the cast chairs:

We already know Logan (Hugh Jackman), older and younger Xavier (Patrick Stewart and James McAvoy), older and younger Magneto (Ian McKellen and Michael Fassbender), Storm (Halle Berry), Kitty Pryde (Ellen Page), Iceman (Shawn Ashmore), Colossus (Daniel Cudmore) and Blink (reportedly Fan Bingbing) were all going to be featured, but slipped into the footage above were seats for Bishop and Warpath!

Lucas Bishop was born in an alternate future where Sentinels roam the Earth and Charles Xavier and most of his X-Men have been eliminated. The remaining mutants are hunted down. James Proudstar (aka Warpath) is an Apache Native American with enhanced strength, speed, durability and senses, and he can fly. Both characters' storylines deal with time traveling and alternate futures -- Bishop actually traveling back in time to meet the X-Men and fixing his future, and Warpath involved with Cable, the son of Jean Grey and Cyclops from an alternate future.

We're assuming that the recent cast additions of Omar Sy and Boo Boo Stewart will play Bishop and Warpath, respectively. In addition, Peter Dinklage will be playing the main antagonist in 'X-Men: Days of Future Past,' plus there's Anna Paquin (Rogue), Nicholas Hoult (Beast), Jennifer Lawrence (Mystique) and Adan Canto (an unknown fiery mutant).

Stay tuned for more updates as they become available, but what do you think about Bishop and Warpath? What do their appearances imply? Sound off in the comments.
