Snowpiercer is a Korean movie directed by Joon-ho Bong based on a french comic book with an american-korean mixed cast. Now that is international.
The trailer seems very interesting giving us some info on the inside relationships developed on the train. We can see that children are taught to worship Wilford (played by Ed Harris) who owns the train. Tilda Swinton’s character has this aristocracy demeanor and governs the train while Chris Evans, Jamie Bell and the rest are the revolutionists who would like things to change in the train.
