South Korean filmmaker Bong Joon-ho's box office hit "Snowpiercer" drew more than 2.5 million viewers in the first four days of its opening, a market tracker said Sunday.
The film, starring top Korean actor Song Kang-ho alongside Hollywood thespians Chris Evans, Ed Harris and Tilda Swinton, attracted more than 840,000 viewers on Saturday, bringing the accumulated total to 2,506,969, according to the Korean Film Council.
The number of local cinemas showing the movie also increased from 848 to 1,101 over the same period.
The film is widely expected to break the 3 million audience mark later in the day.
Based on the French graphic novel "Le Transperceneige," the sci-fi action thriller depicts the inter-class struggles among the world's last-remaining inhabitants aboard a perpetually moving train. (Yonhap News)
