According to the film's distributor Showbox, 'Tunnel' hit the 1,000,000 mark on August 12 at 4 p.m. The rapidity in which 'Tunnel' attracted people to the box office is the same rate as past blockbusters such as 'Veteran' and 'Assassination.'
It's expected that 'Tunnel' will continue to draw big crowds during the National Liberation Day weekend in Korea, raising the box office numbers into the millions.
Meanwhile, 'Tunnel' is a disaster film that tells the story of a man who gets trapped when a poorly constructed tunnel collapses on him, and his struggle for survival. You can watch the trailer for the movie below.
