According to Deadline, Christopher Eccleston (“Doctor Who”) is set to play the villain not named Loki in “Thor: The Dark World.” Eccleston is in final negotiations for the role of Malekith The Accursed, a character known from the pages of Marvel Comics as ruler of the Dark Elves of Svartalfeim. While many fans will say, “You made me at Eccleston,” the news of what character he will play is a positive sign that the “Thor” sequel will indeed be a more other-worldly affair.
