TV fans know Christopher Chung for playing tech specialist Roddy Ho on Slow Horses — he’s at the center of the story in Season 5, with what may have been an attempt on his life already in the premiere, which dropped on Apple TV+ on September 24 — but he also appeared on another well-known series in 2025: Doctor Who.

Chung guest starred in “The Well” as Cassio Palin-Paleen, a trooper who tried going toe-to-toe with the Doctor (Ncuti Gatwa), refusing to listen to his orders and believe his warnings about what was responsible for a series of grisly deaths in a base on a planet.
