Train to Busan (2016)

Train to Busan is a 2016 South Korean zombie action thriller directed by Yeon Sang-ho. The film follows Seok-woo, played by Gong Yoo, a self-absorbed fund manager escorting his young daughter Su-an to her mother in Busan aboard the KTX high-speed train. When a zombie outbreak erupts across South Korea just as the train departs Seoul, the passengers must fight for survival as the infection spreads through the carriages, turning fellow travelers into sprinting, contorting infected that can overwhelm entire cars in seconds.

Yeon Sang-ho used the confined, linear geography of the train to create unbearable tension ��� each car was a potential safe zone or death trap, and the passengers' movement forward through the train became a harrowing gauntlet. The film's emotional power came from its clear-eyed depiction of how crisis reveals character: the working-class husband who sacrifices everything to protect his pregnant wife, the teenage couple who refuse to abandon each other, and the corporate executive who will throw anyone to the zombies to save himself. Train to Busan earned $93 million worldwide and became the film that introduced Korean genre cinema to millions of international viewers, paving the way for Parasite's crossover success three years later.
