Dame Diana Rigg and Rachael Stirling have been cast for a Series 7 episode, it has been confirmed.
The mother and daughter will appear in a 2013 episode, written by Mark Gatiss. The exact character details have not yet been released but the pair will replicate their real-life relationship in the episode by playing a mother and daughter with a dark secret.
Dame Diana Rigg will play a ‘Yorkshire local’. She said: “The first time Rachie and I will be working together is on an episode of Doctor Who specially written for us by Mark Gatiss. How lucky is that?”
Rachael Stirling said: “I am looking forward to the madness of Doctor Who enormously. Mark Gatiss has written a gift of a script and an on-screen relationship between Ma and I that is truly delicious.
“We have never before worked together because the offers have not been tempting, but when such a funny and original script comes through you know the time has come.”
The executive producer of Doctor Who, Steven Moffatt said: “Dame Diana Rigg, Rachael Stirling and a Mark Gatiss script – a combination of talents you could only get in Doctor Who. Frankly, I’m terrified already.”
