Perhaps fitting for a series about a never-ending train ride through the apocalypse, TNT's Snowpiercer has had a heck of a journey to the finish line, but the sci-fi TV show is finally set to hit screens with an official release date. During WarnerMedia's TCA presentation, TNT announced that it will launch the series inspired by the 'Le Transperceneige' graphic novels and Bong Joon Ho's 2013 film adaptation on Sunday, May 31, at 9 pm ET/PT.

The long-developed series stars Jennifer Connelly and Daveed Diggs and has had a five-year path to its premiere, including some key creative changeups along the way. Why? As Diggs said during the TCA panel, it "takes a long time to make really good shit.” Orphan Black co-creator Graeme Manson, who took over as showrunner after Josh Freeman departed over "creative differences," said the series had a "rebirth" when he came on board and that he envisioned an entirely new world from what was originally developed.

“I can’t speak much to the original project because I really wasn’t involved in it at all, but I just loved the movie,” Manson continued. “I loved that tone, I loved the energy, and I loved that it was the weirdest action movie I’ve ever seen. I wanted, above all else, for it to be exciting like that.”

The TCA panel also came with a brand new trailer for the series, which has already been renewed for Season 2 by the network ahead of its premiere. Snowpiercer also stars Alison WrightMickey SumnerSusan ParkIddo GoldbergKatie McGuinnessLena HallAnnalise BassoSam Otto, Roberto UrbinaSheila Vand, and Jaylin Fletcher.

Here's the official synopsis for Snowpiercer:

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 1001 cars, that circles the globe. Class warfare, social injustice and the politics of survival play out in this riveting television adaptation.
