5) Snowpiercer (2013)
Directed by Bong Joon-ho, it takes place in a frozen, post-apocalyptic world where the last survivors of humanity live aboard a constantly moving train. The train is divided into strict class divisions, with the impoverished living in squalid conditions at the rear. The film follows a revolt led by Chris Evans' character, exploring themes of class struggle, inequality, and survival in a confined, oppressive society.
