A group of caboose mutineers begin to pick their way through the carriages to challenge the train’s dictatorial inventor and his minions.
South Korean filmmakers have a thing about train thrillers (see also 2016’s Train to Busan), and this adaptation of the 1982 graphic novel Le Transperceneige feels like Bong Joon-ho has crossed Metropolis (1927) with Runaway Train (1985). In a frozen future caused by a failed bid to halt global warming, Earth’s surviving humans live on an enormous train circumnavigating the glacial planet. A group of caboose mutineers begin to pick their way through the carriages to challenge the train’s dictatorial inventor and his minions.
