Turns out there are few things in this world more delightfully ominous than this menacing whisper from Benedict Cumberbatch: "You think your world is safe. It is an illusion. Enjoy these final moments of peace." That's how the new trailer for J.J. Abrams' Star Trek: Into Darkness opens. The clip finds the Sherlock star playing the film's villain, long rumored to be the notorious Khan. Regardless of his name, Cumberbatch's character is a former Star Fleet agent gone rogue and out for vengeance. Based on the dazzling explosions and action-packed sequences – including Kirk and Spock squeezing a speeding spaceship through a tight space – it looks like he's quite good at causing mayhem. And actually there is one thing that's even more delightfully ominous: Benedict Cumberbatch menacingly murmuring, "I will walk over your cold corpses." Star Trek: Into Darkness is due out May 16th.
