Doctor Who Series 10: 10 Things We Learned From The New Trailer
8. Dalek Water Ghost?
The Daleks have got a lot spookier since Steven Moffat became showrunner. In recent years, they have gained the new party trick of converting corpses into Dalek puppets. In Series 10, they look to be doing something similar - with eerie, water women shouting "exterminate."
The actress in this clip is Stephanie Hyam, who recently appeared in Sherlock. We know that she is to star as Heather in the first episode of the new series, fittingly titled The Pilot. From that, we can guess that the Daleks will be the main enemies of that episode.
It is also likely that the 'Friend from the Future' short that revealed Bill to the world last year will be worked into the episode, as several shots in the trailer seem to take place in the same futuristic corridor setting.
