A spokesperson for TNT told Deadline (opens in new tab), that the show, which is set on a perpetually moving train as it traverses a post-apocalyptic frozen Planet Earth, will end after four seasons. Currently, the third season is available on HBO Max in the U.S. and Netflix in the U.K. and other nations. “We can confirm that Snowpiercer will end after a successful, multi-season run on TNT. Its talented writers, actors and crew took an extraordinary premise and brought it to life in thrilling ways," the spokesperson said. “It was critically acclaimed, had a significant impact on the post-apocalyptic genre and now remains in the hearts and minds of fans forever.” Alongside detailing the post-apocalyptic life on a large train, Snowpiercer builds upon the film’s central theme different passengers split into different classes, with the core plot initially centred around the struggles of the impoverished “Tailies” — led by Daveed Diggs’ Andre — against the indulged first class and Snowpiercer’s Head of Hospitality Melanie (Jennifer Connelly). Snowpiercer picked up momentum in season two, thanks to the introduction of Sean Bean as a somewhat scene-chewing villain, but the events of season three left us with the feeling that it was running out of track. A minor cliffhanger at the end of that season set up some intrigue, but it’s not much of a surprise that the series is pulling into its terminus. What’s not clear here is whether the series has been canceled or has been ended by mutual consent. TNT has reportedly been scaling back its original scripted shows following the Discovery-WarnerMedia merger, leaving the cable network with just Snowpiercer and Animal Kingdom, so the former show’s demise could be due to that same process. Snowpiercer season four has no official release date, but is likely to arrive in 2023. And if you’re craving some retro sci-fi action in the meantime, then check out Stranger Things Season 4.
