Ian McElhinney and Steve Toussaint are set to appear in the two-part finale of Doctor Who Series 12 as the Doctor comes face-to-face with the Cybermen.

With episodes entitled Ascension of the Cybermen and The Timeless Children, the two-part finale sees the Doctor and her friends face one of their biggest and most dangerous challenges yet, but will they be able to defeat one of the Doctor’s deadliest and relentless foes?

Doctor Who Executive Producer Matt Strevens said:
“We were delighted to have Ian and Steve on board the TARDIS for the drama filled two-part finale. Their wide-ranging talent and versatility as actors help bring series 12 to a dramatic conclusion. They were an absolute joy to work with and we can’t wait for viewers to see them in action.”

Ian McElhinney, best known for his roles in Rogue One: A Star Wars Story, The Fall, and Game of Thrones, said:
“I very much enjoyed my time on Doctor Who. The team were a delight to work with and everyone was very supportive and welcoming. All in all it was a blast.”

McElhinney was spotted filming Doctor Who at Nash Point in Wales on August 21.

Steve Toussaint, who is best known for Prince of Persia: The Sands of Time, Judge Dredd, and Mutant Chronicles, added:
“It was an honour to play a part in the giant of British (and World) TV that is Doctor Who. What’s not to like? I had such a great time working with Jodie and ‘the Fam’; another one off the bucket list!”

Written by Chris Chibnall and directed by Jamie Magnus Stone, Ascension of the Cybermen and The Timeless Children will air consecutive Sundays, the evenings February 23 and March 1, on BBC One and BBC America.
