The BBC have announced on Twitter that Dame Diana Rigg is to appear in Doctor Who alongside daughter Rachael Stirling; lead writer Steven Moffat said:
The script commences filming this week, with the pair "playing a mother and daughter with a dark secret". The story is set in Yorkshire, with filming kicking off today at Roath Lock Studios and Bute Town in Rhymney, which stands in for a village in the county.

Diana Rigg is of course best remembered as Emma Peel in the 1960s series The Avengers, and also became James Bond's short-lived wife in On Her Majesty's Secret Service; however the actress has had a long career covering stage, screen and television including The Assassination Bureau, Diana, Bleak House and The Mrs. Bradley Mysteries. She also hosted the PBS series Mystery! for some 15 years.

On her appearance in another sci-fi/fantasy institution, she said:

Meanwhile, her daughter's career has encompassed starring as Nan in the controversial BBC adaptation of Tipping the Velvet, with other television appearances including The Young Victoria, Boy Meets Girl and last year's Women in Love; she has also appeared in films such as Centurion, Salmon Fishing in the Yemen and Snow White and the Huntsman. The actress is also no stranger to the world of Doctor Who, featuring alongside Tom Baker and Louise Jameson, playing Demesne Furze in the recently released Big Finish Fourth Doctor adventure Trail of the White Worm.

On her latest role, Rachael said:

Actor David Warner is to guest star in an upcoming episode of Doctor Who.

The latest issue of Doctor Who Magazine reports that the veteran actor will take a role in a story penned by Who stalwart, Mark Gatiss, which is part of the recording block currently being completed in Cardiff.

Warner has had a long and illustrious acting career appearing in films such as The Omen, Time Bandits, Tron, The Lost World, Titanic and Planet of the Apes. He has appeared in the Star Trek films The Final Frontier and The Undiscovered Country as well as playing Gul Madred in Star Trek: The Next Generation. Although Warner has not appeared on television in Doctor Who before, he has lent his vocal talents to the series when he provided the voice of Lord Azlok in the animated adventure Dreamland, first shown in 2009. He has also appeared in many audio plays for Big Finish Productions, where he has played an alternative version of The Doctor.

The story, due for transmission in early 2013, will be the fifth script for the series by Mark Gatiss, whose last script, Night Terrors, was shown last year. Gatiss told Doctor Who Magazine he was thrilled to be writing for the Eleventh Doctor once more, this time alongside his new companion played by Jenna Louise Coleman. It will be directed by Douglas MacKinnon who directed The Sontaran Stratagem/The Poison Sky in 2008.

The story will also star Irish actor Liam Cunningham, who has appeared in a number of film and television productions including A Little Princess, First Knight, Jude, Dog Soldiers, The Wind that Shakes the Barley, Clash of the Titans, The Guard and the BBC One science-fiction drama series Outcasts, and more recently has become known to international audiences as Ser Davos Seaworth on HBO's Game of Thrones.

Two guest stars have also been confirmed for the previous episode recorded, the first to be filmed with Jenna-Louise Coleman. Written by Luther creator Neil Cross and directed by Jamie Payne, both of whom are making their début on Doctor Who, the episode will star Dougray Scott and Jessica Raine.

Scott is a Scottish actor who has appeared in films such as Enigma, Desperate Housewives and, recently, in My Week With Marilyn , while Raine is best known for playing the lead role of nurse Jenny Lee in the BBC1 drama series Call The Midwife.

An updated cast list for each story can be found in the Doctor Who Guide.

Outnumbered star Claire Skinner will be joining the Doctor Who team for the 2011 Christmas Special. Skinner, who was spotted last week filming for the special, will play a super-mum, Madge Arwell, in the story set in the middle of winter during World War II.

Showrunner Steven Moffat promises the episode will be the 'most Christmassy ever' with a chase through a 'Lion, The Witch And The Wardrobe' type forest, complete with an ice villain. The story sees the Doctor acting as the caretaker of a creepy old house in Dorset before embarking on an adventure with Madge and her two children Lily and Cyril.

Moffat said how much he enjoyed writing the Christmas special for Matt Smith:

Joining Skinner will be comedian and presenter Alexander Armstrong (who also plays Mr Smith in The Sarah Jane Adventures), Fast Show veteran Arabella Weir, and comedian Bill Bailey, who said on Twitter:
