Doctor Who writer Neil Cross has revealed he will be returning to pen more episodes in series eight, saying: "I am going back."
The Luther and Spooks screenwriter, who is based in New Zealand, said: "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 [Moffat] 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."
Cross penned series seven episodes The Rings of Akhaten and Hide, which starred departing Doctor Matt Smith and his new companion Clara, played by Jenna Coleman.
And while Cross may be "sad not to have the opportunity to write for Matt Smith again" (he calls the 30-year-old "the most outstanding Doctor to date") that doesn't mean he's not looking forward to the challenge of penning adventures for a new Doctor.
"I am really excited about writing for Peter Capaldi," said Cross, speaking to New Zealand news website stuff.co.nz. "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."
Matt Smith is leaving Doctor Who at the end of this year after the hit show celebrates its 50th anniversary. Peter Capaldi is expected to make his entrance as the new Doctor during the Christmas special.
