After weeks and weeks of teasers, the first full trailer for the next season of Doctor Who has finally landed. In this new spot, Capaldi really gets to stretch his legs a bit in his new role as the 12th Doctor. But more than anything, there's a bit more gravitas to this incarnation, as he tells his companion Clara Oswald that he's taking them "into darkness." We can't wait for the premiere on August 23rd.
