The film's main antagonist Bolivar Trask, creator of the mutant hunting Sentinels, is best known for his appearance in DOFP, but he actually appeared in the Last Stand first. Played by Bill Duke, this version is simply referred to as Trask, but Bryan Singer confirmed that he is in fact Bolivar. This raises several questions, the least of which is how he has aged so little in fifty years. The DOFP version of the character is played by Game of Thrones star Peter Dinklage, who obviously bares no resemblance to his Last Stand counterpart. Since that version played a major role in DOFP, whereas the Bill Duke version was only a minor character thrown in to an already overcrowded movie, hopefully few would have noticed the character in the Last Stand. Still, those of us who did notice demand answers. And we demand them now!
