A Surprise Ending for Clara?

Filming on the Christmas special is now taking place but Jenna Coleman is refusing to confirm any involvement beyond Series 8. She told the Radio Times the reason why is that it would spoil a surprise coming up.

“There’s lots of rumours. We’ve sat down with [showrunner] Steven Moffat and we’ve all decided we don’t want anyone to know which way it’s going,” she said.

Adding: “If you know I’m in the next series – or if you know I’m off – you’ll know how the story ends.

“There’s a surprise we’ve got coming, it’s much better that nobody knows which way it’s going to go – so that’s where we’re trying to keep it at the moment.”

UPDATE: In the same article Jenna added: “I’ve been working too hard. There’s not even time for auditions or anything. I’m filming till October.”

On Series 9: “They start filming in January.”
