Darkness is most certainly coming in the third and final trailer for the highly-anticipated sequel Star Trek Into Darkness. Captain Kirk's (Chris Pine) rebellious ways are put on full display in this latest footage, when he sets off on an unsanctioned quest to take down the terrorist John Harrison (Benedict Cumberbatch). Hell hath no fury like a Starfleet captain scorned, as seen in director J.J. Abrams' sci-fi thriller, in theaters May 17.
