Maybe that’s why Snowpiercer is both oddly comforting and joltingly strange. The English-language debut of acclaimed Korean director Bong Joon-ho (The Host, Mother), it chronicles the plight of Earth’s few remaining survivors, who are all huddled on a train that’s been traversing the planet for the last 17 years. Based on the 1982 French comic book Le Transperceneige, Snowpiercer stars Chris Evans (Captain America from The Avengers) as Curtis, the reluctant leader of those who live in the caboose section of this lengthy locomotive. He’s joined by Edgar (Jamie Bell, Turn), who idolizes Curtis, and Tanya (The Help’s Octavia Spencer), whose son was taken by the storm troopers who police the train.
