Drop your Susan, Jenny, Rani and Chloe Webber speculation right now! Steven Moffat has said that Maisie Williams is playing a new character and is definitely not a returning character.

Speaking at the Television Critics Association’s press tour Moffat said: “Once you see what she’s up to you’ll appreciate what a clever idea [the role] was. It’s a significant role, we’re not just throwing her away. It’s a great part and she’s terrific in it.

He adds: “One thing I think is worth saying, because it keeps coming up as an issue, is that she is not playing a returning character. She’s a new character, she’s not a character from the Doctor’s past.”

Another “Ask the Execs” video has also been released today with Steven Moffat and exec producer Brian Minchin briefly discussing Williams’ casting.

It was Minchin’s idea to cast Maisie after seeing her captivating performance in “Cyberbully”. Moffat had an idea for a fantastic character and it just gelled. Moffat adds that Maisie provides a fantastical contrast to Capaldi – “It’s like a grand old Victorian actor opposite a Youtuber. They work beautifully together.”
