Roll up, roll up, see Benedict Cumberbatch as you've never seen him before in the new trailer for J.J. Abrams' Star Trek Into Darkness. The British actor, best known for playing Sherlock Holmes in the BBC's much vaunted series, plays mysterious villain John Harrison in the action sci-fi flick and is seen wreaking havoc in London throughout the trailer.

It's credit to the cast and crew of Into Darkness that little is known of Cumberbatch's character. Rumors last year suggested he was reprising the classic Star Trek villain Khan, though that now appears wide of the mark. The trailer gives little away as to his identity, though the actor is seen sporting a long black coat and throwing various menacing stares. "You think your world is safe, it is an illusion, enjoy these final moments of peace," he cryptically warns in the opening scene before asking, "Your commanders have committed a crime I cannot forgive, none of you are safe. Have I got your attention now?"

Elsewhere, we see Chris Pine's James T. Kirk on the hunt for revenge after Harrison's attack on the British capital, telling the villain he will pay for his crimes. In one scene, he's heard uttering the immortal line included in pretty much every action sci-fi flick ever made, "I have no idea what I'm supposed to do, I only know what I can do."

The whole thing is shaping up to be an intriguing sequel to Abrams' 2009 movie Star Trek. There's plenty of impressive futuristic cityscapes, huge explosions and people running away from, err, things.  It even looks - dare we say it - very Cloverfield in places. 

Catch Star Trek: Into Darkness when its hits on May 17, 2013.
