According to Hypable on Jan. 5, it appears that Bryan Singer's "X-Men: Days of Future Past" script has leaked a certain excerpt revealing a character's death. Since there is a time travel element entailing the theme of the film, Singer has opened up wide range of possibilities when it comes to killing off characters. The character, though seen very little in previous "X-Men" films, meets a grim demise.
For those who may not remember the character's cameos, he was played by actor Daniel Cudmore in "X2: X-Men United". He was seen escorting younger mutant students through a hidden passage that lead outside of Xavier's school when it was being ransacked by Stryker's soldiers.
Colossus also appears in "X-Men: The Last Stand" as he participated in a simulated arena known as The Danger Room at the institute as well as holding the line as he helped the rest of the mutants who were up against Magento's Brotherhood of Mutants.
"X-Men: Days of Future Past" releases in theaters on May 23.
