Ironically, the show, like the movie, is set in a post-apocalyptic world that passengers are told has been frozen after scientists’ attempt to course-correct the rising temperatures of climate change went wrong. After last year’s dangerous, record-breaking summer heat, British Columbia is once again seeing the impacts of the very issue the “Snowpiercer” story aims to address. Vancouver, Canada in particular is a popular filming spot for American television shows, so hopefully everyone on “Snowpiercer” and other Canadian sets will stay safe as the heat wave continues.

The show centered the topic of extreme global temperatures more than ever in its third season, which saw Layton and others discover a temperate climate outside the train called New Eden. The third season ended with Cavill — who returned after her fake-out death in the second season finale — staying on the train with some passengers aboard the Snowpiercer while Layton led others towards the uncertain future of New Eden.

The production halt, while obviously critically important, also marks another setback for a series that has been riddled with delays and production issues from the beginning. “Snowpiercer” is based on Bong Joon-Ho’s critically acclaimed film of the same name (which in turn was based on the graphic novel series “Le Transperceneige”) and has so far released 30 episodes to date. But in the process, the show has also suffered from creative shake-ups, COVID-19 related delays, a confusing network switch-up (a move to TBS was planned, then reversed), and more. At this point, the series is set to be the last scripted show standing at TNT, a network whose lineup was effectively gutted after the Warner Bros. Discovery merger earlier this year.

“Snowpiercer” airs on TNT. Its final season premiere date has not yet been announced.
