Da Rhythm Rebel
All Star
It's clearly not the same Trask. He was not alive during X-MEN 3. Mystique kills Trask but gets captured by Stryker, they experiment on her and start making the Sentinels, which are perfected after the original trilogy.
wrong
there was a huge uproar initally that Dinklage was being cast as Trask when Bill Duke was already cast as THE SAME CHARACTER in X3. So back to my point, at the beginning of the film, in the future Xavier tells all of them that Mystique killed Trask back in '73 thus starting them on the path that lead to where they were in the future...IMPOSSIBLE BASED ON X1 - X3 as that bit of history was NEVER cannon in the movies. sorry that's a big flaw for the entire series now.
