Slow Horses actor Christopher Chung to star in next series of Doctor Who

Slow Horses actor Christopher Chung is to star in the forthcoming series of Doctor Who.

Australian film and TV star Chung, 36, best known as MI5 agent Roddy in the popular spy series, will play Cassio in a new adventure airing later this year.

His character will meet the Time Lord, played by Ncuti Gatwa, and Belinda Chandra (Varada Sethu) – who is another new addition to the sci-fi show.

Showrunner Russell T Davies said: “I’m a huge fan of Slow Horses, and I was so excited to get Chris involved.

“He brings all of his strength and style and talent to one of the darkest, toughest episodes we’ve ever made.

“As for whether Cassio is an ally or an enemy of the Doctor, you’ll have to wait and see, but I can promise, it’s one hell of a meeting!”

Chung said: “I’m absolutely thrilled to step into the Whoniverse as Cassio for season two.

“This show is legendary, and getting to be part of this new era feels surreal.

“Working with Russell and Ncuti has been a dream.

“This episode is huge – packed with everything Who fans love: heart, adventure, and a touch of madness.

“I can’t wait for everyone to see what’s in store – it’s going to be iconic. Get ready!”

Chung also played Fred in Sir Steve McQueen’s Second World War film Blitz and has starred in West End musical Heathers.

Gatwa’s first series as the Time Lord premiered on May 11 last year with a double bill.

In series two, the Doctor meets Belinda (Sethu) and begins a quest to get her back to Earth, with a mysterious force attempting to stop their return.

Doctor Who will air on BBC One and BBC iPlayer in the UK.
