Neil Cross, writer of The Rings of Akhaten and Hide, has confirmed to Stuff that he is planning on returning to write at least one series 8 episode.

“I am going back. I have got story ideas tucked away, but if I told you about them I would have to kill you. There’s a whole bunch of stuff I want to do. Steven is clearly very busy with the 50th anniversary special and Christmas special, but I have to find out from Steven what his intentions for the Doctor are and what sort of stories he wants me to write.”

He also commented on Peter Capaldi as the Twelfth Doctor, saying "I am familiar with Peter Capaldi's work and I am looking forward to it. Peter has presence on the screen. I think he's an outstanding choice. There's something about his physicality, his image, his wit, that evokes the Doctor. There's something about him that evokes classic Doctor Who."
