Snowpiercer season 3 is on route, following a hugely successful TV adaptation of Bong Joon-ho's 2013 post-apocalyptic film of the same name. The first two seasons originally premiered on Netflix, but it has since moved to TNT.

Sam Linsky and Adrienne O’Riain, co-heads of scripted original programming for TBS, TNT and truTV said: "Snowpiercer has been an incredibly successful series for us that continues to capture the imagination of viewers, grow audience and maintain strong ratings."

In addition to news of a third season, they have confirmed that Snowpiercer has already been renewed for a fourth, adding: “All of our seasons embark on an emotional, unexpected ride and the well-plotted storylines will continue to evolve and remain relevant to audiences. We’re excited to keep the train running into Season Four."
