The comments were made during a Q&A session as part of the Series 8 DVD launch earlier this week, where Moffat said:
“Santa could never be evil, for heaven’s sake! Santa is both real and a Christmas hero.He then went on to talk about the casting of Nick Frost in the role, claiming:
“No no, don’t worry any parents who were worried about that. Santa is presented, as he is in real life, as a great Christmas hero.”
“He actually is the real Santa. He’s been faking it up until now. For the first time he’s allowing the natural colour of his beard to show through.Viewers caught a first glimpse of Frost's Santa at the end of the Series 8 finale Death in Heaven, whilst a special preview clip featuring the character alongside the Twelfth Doctor (Peter Capaldi) and Clara Oswald (Jenna Coleman) aired last week as part of the BBC's Children in Need appeal night.
“You could figure it out, you know, Nick Frost, Nicholas Frost – you see?”
