What appear to be excerpts from the "X-Men: Days of Future Past" script have been leaked online.
Radar Online is one of three sources who claim they've received leaked script materials from the upcoming high-profile sequel, materials which indicate what is going on in the early scenes of the film.
Though there's still no verification as to the authenticity of the excerpts, at least two of those sources have reportedly been asked by Fox to remove said materials from their sites - indicating they could well be accurate after all.
Assuming they are real, the potential spoilers include:
The near-future scenes are set around a crumbling, ruined Moscow where a vast bomb shelter under the Kremlin serves as a refuge for mutants. James 'Warpath' Proudstar (BooBoo Stewart) and Blink (Bingbing Fan) are the first mutants on screen while it sounds like the Sentinels find the refuge almost right away.
Another leaked excerpt indicates that Colossus (Daniel Cudmore) takes on one of the advanced future Sentinels, a fight that will leave him seriously injured.
Of course, as it's a time travel movie the consequences - even potential deaths - are all up in the air and reversible until the final few minutes of the film.
