Ahead of itsSeason 3 finalecomes news that production onSnowpiercerSeason 4 is already underway in Vancouver with a new showrunner at the helm and some familiar faces joiningDaveed DiggsandJennifer Connellyin front of the camera. There are no details on their respective roles at this time. Agent Coulson himself,Clark Gregg, the veteran ofIron Man,Iron Man 2,Thor,The Avengers, and, for most of its seven-season run,Marvel’s Agents of S.H.I.E.L.D.will step onboard TNT’s chilly post-apocalyptic ride. Also incoming is Tony Award winnerMichael Aronov, who’s made his mark onThe Americans,The Blacklist, and, most recently,Hit & Run.
Corralling them, the returning cast, and the show’s spiraling plotlines will be new showrunnerPaul Zbyszewski, who’ll be stepping in for departing executive producersGraeme MansonandAubrey Nealon. Manson, a co-creator ofOrphan Black,replacedJosh Friedmanin 2018. Zbyszewski is a genre veteran showrunner with stints on Hulu’sHelstrom, ABC’sLost, andAgents of S.H.I.E.L.D.,where he overlapped with Gregg.

“I’m so grateful to everyone at TNT and Tomorrow Studios for letting me join the riveting world ofSnowpiercerthat Graeme and Aubrey have so beautifully crafted and built,” said Zbyszewski. “We have an exciting fourth season planned, and I can’t wait to be on set with such an incredible cast and crew as we continue to explore new worlds, create new mysteries, and develop character relationships.”

Zbyszewski will join producersChristoph Schrewe,Marty AdelsteinandBecky Clements,Matthew O’Connor,Ben Rosenblatt, andScott Derrickson, as well as the slate of Korean creators who brought us the2013 film on which the series is based, including directorBong Joon Ho,Miky Lee,Jinnie Choi,Park Chan-wook,Lee Tae-hun, andDooho Choi.
With Mason and Nealon at the lead,Snowpiercerhas managed to offer new possibilities and fresh drama out of source material constrained and limited by design (it happens on atrain, after all). Some of that has come through tapping into the graphic novel that inspired the original film. Some of that has come through pure invention. Overall, it’s been a consistent surprise.
As the departing showrunners said in a joint statement, “We have been blessed with an abundance of riches in building the world ofSnowpiercer– from the incredible cast and crew, to the loyal fanbase and the building blocks afforded from the film and graphic novel. Tonight’s finale is the culmination of several storylines, with unexpected twists and turns around every corner, and leading to an exciting fourth season with Paul’s vision and creative storytelling continuing the incredible show momentum.”
The final episode of their run—and the current Season 3—airs tonight on TNT at 9 PM EST. There’s no word yet on the release date forSnowpiercerSeason 4.
