We see themes of class differences yet again in Snowpiercer. Basically, an experiment to stop global warming wipes out humanity, and so now survivors board onto a global train ran by a perpetual motion engine. A revolution ensues to democratize the train's resources, which have been mainly delegated to elites. Chris Evans leads the film, with support from A-listers such as Song Kang-ho (Mr. Kim from Parasite) and Octavia Spencer.
