We've had teasers, we've had fan made mashups, but this is the real deal: our first real look at the Twelfth Doctor and Clara in action!

The jam packed trailer is full of interesting clips - half cyborg victorians! Explosions! Orange-lit console! A DINOSAUR!! - and it all seems so far away at the moment, but rest assured, he's a-comin'... and as the new Doctor himself says, we're heading into the darkness. Excited?

Doctor Who returns August 23rd with the feature-length episode Deep Breath, on BBC One and BBC America.
