At the San Diego Comic Con two more episode titles were revealed. Episode two written by Chris Chibnall is titled Dinosaurs on a Spaceship and episode Three written by Toby Whithouse is called A Town Called Mercy.
It is also rumoured that the series will start on August 25th or September 1st (TBC)
Steven Moffat said:
Dinosaurs On A Spaceship - what more do you need? The Doctor will come face to face with some of the most monstrous creatures evolution has ever produced, on some of the most monstrous sets we've ever built. We took one look at Chris Chibnall's brilliant script and said to ourselves: "We're going to need a bigger corridor".
And Toby Whithouse's A Town Called Mercy takes us into a genre Doctor Who hasn't attempted since the Sixties - it's a full-blooded Western. We knew from the start we needed some serious location shooting for this one, and given the most iconic American setting imaginable there was only one place to go - Spain.
