Russell T Davies has confirmed that Christopher Chung is to join the Whoniverse in the next season of Doctor Who.
Chung, best known as MI5 agent, Roddy Ho, in Apple TV’s Slow Horses, he’ll meet Doctor (Ncuti Gatwa) and Belinda Chandra (Varada Sethu) for a new adventure set to air this year.
“I’m absolutely thrilled to step into the Whoniverse as Cassio for Season 2!” said Chung.
“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 has appeared alongside Gary Oldham in Slow Horses since 2022 and recently appeared as Fred in Steve McQueen’s Blitz.
His West End credits include Kurt Kelly in Heathers: The Musical.
“I’m a huge fan of Slow Horses, and I was so excited to get Chris involved,” added Russell T Davies, Showrunner.
“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!”
The series is produced by Bad Wolf with BBC Studios for the BBC and Disney Branded Television, and will air on BBC One and BBC iPlayer in the UK, and exclusively on Disney+ outside of the UK.
