Doctor Who supremo Steven Moffat has said it was an "easy decision" to bring back the Daleks for the new series.
He said the villains with the distinctive metallic speech "sum up the whole series just by being there".
He said: "We've been off the air for longer than usual, so it was an easy decision to come back with Doctor Who at its most iconic and that means Daleks, lots and lots of scary Daleks."
The new series also sees the Timelord, played by Matt Smith, get to grips with dinosaurs, and hitching a ride on the back of one of the creatures caused him a few problems.
He said: "I had to wear padded trousers. Dinosaurs are a lot lumpier than horses, so it was a painful couple of hours, a laugh though and definitely worth it as it's going to look great."
The new series will also feature a range of guest starts including Steven Berkoff and Jemma Redgrave.
