Snowpiercer season 4: complete season guide, trailer, cast and everything we know about the final season

Jennifer Connelly as Melanie Cavill in a control room setting in Snowpiercer season 4.

The epic journey comes to an end in Snowpiercer season 4. AMC, the home of The Walking Dead franchise, Interview with the Vampire, Orphan Black: Echoes and Monsieur Spade, picked up the first seasons of the sci-fi epic and ordered a fourth and final season to allow the journey to play out for fans.

Snowpiercer, the story of a perpetually moving train circling the earth with the last remaining humans onboard is based on a graphic novel series from Jacques Lob and Jean-Marc Rochette, as well as a movie from Parasite director Bong Joon Ho. 

The series originally aired on TNT. The network ordered a fourth and final season, but parent company Warner Bros. Discovery shocked fans with the decision not to release the already produced final season in a cost-cutting movie. Fortunately, unlike the Batgirl movie that was shelved at WBD and will never have a chance to be seen, Snowpiercer's producers were able to shop around for a new home and AMC was quick to offer one. 

The first three seasons will be available on AMC Plus in June, ahead of the final season's July premiere. 

Here's everything we know about Snowpiercer season 4.

Showrunner Paul Zbyszewski noted that in wrapping up the show, the goal was to reveal what the future holds for the passengers. "Season 4 is the future," he said.

Snowpiercer season 4 premise

Here's what AMC says about the premise of Snowpiercer season 4: 

"Set more than seven years after the world has become a frozen wasteland, Snowpiercer centers on the remnants of humanity who inhabit a perpetually moving train, with 1,001 cars, that circles the globe. Class warfare, social injustice and the politics of survival play out in this riveting television adaptation based on the graphic novel series by Jacques Lob and Jean-Marc Rochette, and the film from Oscar-winner Bong Joon Ho (Parasite).

"The action-packed finale of season three left a split of the train with Melanie Cavill (Jennifer Connelly) leading the Eternal Engine and those passengers who chose to stay aboard Snowpiercer for relative safety, and Andre Layton (Daveed Diggs) leading the others on Big Alice who chose to adventure to the unknown, outside world of New Eden."
