Doctor Who Series 8 writer Jamie Mathieson has revealed that he has written two episodes for the first Peter Capaldi series. On his blog, Mathieson said:
“So… they quite liked the first script I delivered and
asked me if I’d like to write another. They quite liked that one too.
Then they decided to put them next to each other in the schedule as episodes 8 and 9.”
Episode 8 is directed by Paul Wilmshurst and stars Frank Skinner (The Five(ish) Doctors Reboot), David Bamber (The King’s Speech), Daisy Beaumont (Star Stories), Janet Henfrey (The Curse of Fenric) and Christopher Villiers (Emmerdale) whilst Episode 9 is directed by Douglas Mackinnon.
