The ‘Slow Horses’ star joins the Whoniverse
Actor Christopher Chung is joining the cast of Doctor Who Season 2 as a character simply known as ‘Cassio’. He will meet the Doctor (Ncuti Gatwa) and new companion Belinda Chandra (Varada Sethu) for a thrilling adventure in the forthcoming second season – described by showrunner Russell T Davies as one of the “toughest episodes we’ve ever made”.

Best known as tech-savvy MI5 agent Roddy Ho in the Apple TV+ drama Slow Horses, alongside Gary Oldman, Chung is an Australian actor who has also starred in the likes of BBC’s Waterloo Road, and the Steve McQueen 2024 movie, Blitz.

On the casting, Russell T Davies stated: “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!”
Christopher Chung said: “I’m absolutely thrilled to step into the Whoniverse as Cassio for Season 2! 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!”
