It had to be on here. The return of the Doctor's most iconic foe. And what makes this trailer so brilliant is just how little of the Dalek it shows. As the trailer begins, it seems we're being given a nice adventure in some kind of museum full of aliens. But it soon becomes clear that this isn't going to be a whimsical adventure. We're repeatedly teased with the idea that whatever happens here, it's going to be realy bad. Something really dangerous is brewing. And then the two golden moments. Christoper Eccleston's Doctor shouts at something, telling it to 'Just Die!!!'. In what possible situation would the Doctor, lover of all life say this? It must be something really bad. And then it's revealed, at the very end of the trailer, the chilling and iconic battle cry of the Doctor's greatest enemies. 'Exterminate!!' Back for the first time in this new version of the classic show. The Daleks.
