Earlier today, excerpts from the X-Men: Days of Future Past screenplay were leaked to various news outlets, which proved to offer up a few spoilers for this summer's highly-anticipated franchise sequel. Be warned, if you don't want to learn any more about the X-Men: Days of Future Past plot, stop reading right now.

The first excerpt that was leaked to Radar Online teases the opening of the movie, which features new mutants Warpath (BooBoo Stewart) and Blink (Bingbing Fan). Warpath gets the film's first line of dialogue, saying "They're here," right before they are both swiftly transported to a bomb shelter underneath the Kremlin.

The script adds details such as the fact that shelves are stocked with food and bunks are filled with refugee mutants, along with a shrine to their fallen comrades. When Blink enters the room, she says, "Time's up," as "massive deep shockwaves" echo from above.

While it isn't explicitly said in this excerpt, these shockwaves are likely coming from the Sentinels, robots created by Bolivar Trask (Peter Dinklage) to hunt down all mutants. Radar Online's source was only identified as a member of the movie's production staff, who is reportedly one of 100 people who has access to the 400 printed copies of the script.

This first excerpt clues us in that the story starts out in Moscow, which leads us to the second excerpt dealing with Colossus (Daniel Cudmore), a character who was actually born in Russia in the Marvel comic books. The passage essentially details a battle between Colossus and a Sentinel, where the character is crushed by the massive robot. It isn't known for sure if Colossus dies, or if this scene will even make it into the final cut. However, 20th Century Fox asked ThinkMcFlyThink to remove the excerpt, which lends credence to its authenticity. Daniel Cudmore played Colossus in X2: X-Men United and X-Men: The Last Stand before reprising his role in this sequel.

It's also worth noting that, since the story features a great deal of time travel, these scenes are just a glimpse at a possible future which is seen by Professor Xavier (Patrick Stewart). It's also possible that several characters will die in these future scenarios, before Wolverine (Hugh Jackman) gets sent back to fix the timeline.

Even if this is an authentic script draft, it may not even be used in the final cut. We reported last month that director Bryan Singer has already cut out Anna Paquin's character Rogue during the editing process.

Of course, none of these details have been confirmed by 20th Century Fox. We'll just have to wait until May 23 to find out which of these mutants live to fight another day in X-Men: Apocalypse.
