Check out the trailer for the fourth and final season of Snowpiercer. The series stars Jennifer Connelly, Daveed Diggs, Sean Bean, Rowan Blanchard, Alison Wright, Mickey Sumner, Iddo Goldberg, Katie McGuinness, Lena Hall, Sam Otto, Chelsea Harris, Mike O’Malley, Roberto Urbina and Sheila Vand.

Previously announced new cast members for Season 4 include Clark Gregg (Agents of S.H.I.E.L.D., The Avengers, Thor) and Michael Aronov (The Drop, The Americans, Operation Finale).

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 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 3 left a split 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 choosing to adventure to the unknown, outside world of New Eden.

Snowpiercer Season 4 is executive produced by Paul Zbyszewski (Lost, Agents of S.H.I.E.L.D, Helstrom), Christoph Schrewe; Marty Adelstein, Becky Clements and Alissa Bachner through Tomorrow Studios; Matthew O’Connor, Ben Rosenblatt and Scott Derrickson, along with the original film’s producers Bong Joon Ho, Miky Lee, Jinnie Choi, Park Chan-wook, Lee Tae-hun and Dooho Choi. The show is produced by Tomorrow Studios (an ITV Studios partner) along with CJ Entertainment. ITV Studios distributes Snowpiercer internationally.

The final season of Snowpiercer premiers on Sunday, July 21 at 9pm ET/PT exclusively on AMC and AMC+.
