The upcoming six-part series - which sees Jodie Whittaker's Doctor teaming up with Yasmin Khan (Mandip Gill), Dan Lewis (John Bishop) and Vinder (Jacob Anderson) - will see Rochenda, Sue and more as guest stars joining the cast.

The pair have been confirmed by the BBC alongside 'The End of the F****** World' star Steve Oram, 'Ripper Street' actor Craige Els and Innocent's Nadia Albina.

Also set for guest roles in the upcoming series are Sam Spruell ('Small Axe'), Jonathan Watson ('Two Doors Down') and Paul Broughton ('Brookside').

BBC is keeping the actors' specific roles under wraps ahead of the series launching on Halloween (31.10.21), but plenty of other stars have already been confirmed.

A new preview for the six-episode serial, it was revealed that the Sontarans, Weeping Angels, Cybermen, and the Ood will all be back for scares, along with the new monster, Karvanista.

What's more, 13 cameo stars were confirmed by BBC One, including Robert Bathurst, Thaddea Graham, Blake Harrison, Kevin McNally, Craig Parkinson, Sara Powell, Annabel Scholey, Gerald Kyd and Penelope Ann McGhie.

'Downton Abbey' star Robert Bathurst said: "People say 'Doctor Who' is science fiction. Fiction? No it's all real, and it's as scary to do as it looks. Great to be part of it."

'The Inbetweeners' actor Blake Harrison said: "It's a pleasure to be a part of this huge show that has such a passionate fan base! I hope all the 'Doctor Who' fans enjoy the new series and my role in it."

'Pirates of the Caribbean' actor Kevin McNally said: "I am thrilled to be helping the Doctor put the universe to rights in the latest season of 'Doctor Who'."

'Line of Duty' star Craig - who has also appeared in 'Misfits', 'Whitechapel' and more - commented: "I feel tremendously lucky to have joined the 'Doctor Who' family this season. Chris' scripts are witty, intelligent and full of light and shade, making my job as an actor extremely enjoyable! My son loves the show and as long as he gives me his seal of approval I'll know I've done it justice!"

While 'Being Human' star Annabel Scholey gushed: "I am absolutely thrilled to be a part of the 13th series of 'Doctor Who'. It was a lot of fun to film and I enjoyed every minute I spent with the amazing cast and crew...Halloween will be that little bit more spooky this year!"
