Director Yeon Sang-ho's adrenaline-filled Train to Busan premiered at this year's Cannes Film Festival.

The film, which took a record $5.76m on its opening day in July 22, has grossed $38.8 million in its first five days, an all-time record for the Korean box office. So far, the film has grossed $63.9 million in South Korea alone.

It is set to open in cinemas across Asia this week.

The movie starts off with an innocent enough train journey, until a viral outbreak outside starts to infect passengers on board a bullet train to the city of Busan, turning them into the undead. The Korean government eventually declares a state of emergency and martial law.
