"The Pirates" has stopped the record-breaking sweep of "Roaring Currents" to belatedly top the box office three weeks after its release on Aug. 7.
Given that a movie's box-office rankings usually decrease with time, the unusual achievement of "The Pirates" raises expectations of how far it can chase "Roaring Currents."
As of Tuesday, the former drew 6.05 million viewers, while the latter became the most successful Korean film of all time with 16.35 million viewers, since its release on July 30.
"The Pirates" has continued to attract moviegoers at a steady pace, hitting the 1 million mark on its fourth day and the 4 million mark on its 12th day.
It will likely maintain its momentum as no other blockbusters, except for the "Ninja Turtles," are set to be released ahead of Chuseok, or Korean Thanksgiving.
It remains to be seen whether Korean films will continue to sweep the box office during one of the nation's biggest holidays from Sept. 7-10. Next week, two Korean movies -- "My Brilliant Life" starring Kang Dong-won and Song Hye-kyo and a sequel to the gambling flick "The War of Flower" -- will hit cinemas. Luc Besson's latest film "Lucy" starring Choi Min-sik and Scarlett Johansson will also be released.
