The special titled Eve of the Daleks will see the Irish comedy favourites join Adjani Salmon in this guest star line up. The show will also feature Liverpudlian comedian John Bishop.
Aisling Bea is of course known for appearances in comedy shows like 8 Out Of 10 Cats Does Countdown.
The special's synopsis reads this, "Sarah (Aisling Bea) owns and runs ELF storage, and Nick (Adjani Salmon) is a customer who visits his unit every year on New Year's Eve".
"This year, however, their night turns out to be a little different than planned as they find themselves joining forces with the Doctor, Dan and Yaz in a fight against the Daleks".
The BBC also released this statement, "Following the explosive series finale of Doctor Who: Flux, The Thirteenth Doctor (Jodie Whittaker) and friends Yaz (Mandip Gill) and Dan (John Bishop), will kick-start 2022 with an action-packed spectacular episode set to air on BBC One on New Year's Day".
Showrunner Chris Chibnail added, "We all need a little romance in our lives around New Year. Less so, Daleks".
He added, "But Aisling Bea and Adjani Salmon's characters will have to deal with both in a New Year's Eve from Hell".
"Together with Jodie Whittaker's Doctor, it'll hopefully prove the perfect New Year's Day tonic".
No details over Pauline McLynn's character has been announced. Where do we know her from?
