Snowpiercer is a new TV show based on the 2013 film of the same name. The film was directed by Bong Joon Ho, who has since won an Oscar for Parasite.
This video shows the official trailer for the Snowpiercer TV show, which stars Jennifer Connelly, Daveed Diggs, and Mickey Sumner.
Snowpiercer tells the story of a huge train which constantly travels the world after it turns into a frozen wasteland. All human survivors are on board.
This is all about class struggle, with the rich at the front of the train complaining about sauna etiquette, and the poor at the back of the train begging for food.
