'Doctor Who': Matt Smith, Jenna-Louise Coleman Snapped Filming With Dame Diana Rigg

Doctor Who stars Matt Smith and Jenna-Louise Coleman have been snapped filming with Dame Diana Rigg in Butetown Village, Rhymney, in Wales.

It was announced on Monday that The Avengers star Rigg would be teaming up with her actress daughter Rachael Stirling onscreen for the first time to star in the cult sci-fi series.

The stars' relationship will be mirrored on the show when they play a mother and daughter "with a dark secret" after writer Mark Gatiss penned an episode with them in mind.

Shooting for their scenes together began in Wales this week, and Rigg is delighted to finally be sharing the screen with her 35-year-old daughter.

She told the BBC: "The first time Rachie (sic) and I will be working together is on an episode of Doctor Who specially written for us by Mark Gatiss. How lucky is that?"

And Stirling added: "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 episode will air next year.
