Big Trouble vs X-Men Last Stand

Stories of cops, criminals, kids, and others intersect in the comedic movie:  Big Trouble.  Mutants are given the choice of taking a pill and losing their powers, or fighting humans (I guess).  Also, there's a mutant who becomes a more dangerous mutant whilst being entangle in a love triangle (I guess) in X-Men The Last Stand.  Ben Foster(?) gets the Box Office treatment this episode.
