A TV series remake debuted in 2018 produced by Media Asia and former TVB producer Tommy Leung. The series, which is titled "Infernal Affairs" like the film, stars Gallen Lo, Damian Lau, Paul Chun, Lo Hoi-pang, Eric Tsang, Derek Kok, Dominic Lam, Toby Leung and Yuen Biao. The TV series uses the same concept as the film, but with an entirely new story and characters, and the setting expanded beyond Hong Kong to include Thailand and Shezhen. It stretched through three seasons with each season consisting of 12 episodes.
