The 45 minute story features almost every Dalek design from the history of Doctor Who - including the Special Weapons Dalek.
Executive Producer Caroline Skinner said: "This is an epic Dalek adventure that kicks off the new series in explosive style! If you think you know all there is to know about the Daleks, think again…"
