SEOUL — Period actioner “Roaring Currents” maintained a firm grasp at the top of the South Korean box office and became the most watched film of all time during its third weekend.

Despite competition from “The Pirates” and new release “Sea Fog” (aka “Haemoo”) handled by Lotte and N.E.W respectively, CJ Entertainment’s “Roaring Currents” dropped only 27% and added 2.06 million admissions, for a cumulative score of 14.62 million in ticket sales.

In cash terms, it earned US$16.1 million (KRW16.4 billion) and finished the weekend with a $111 million (KRW113 billion) cumulative.

“The Pirates,” a rival sea actioner which opened on Aug. 6, saw some benefit from a slightly weakening ”Currents.” It dropped only 17% and saw its market share climb from 26% to 29%. Advanced ticket sales are reportedly weakening, but the film has now captured 4.29 million ticket sales and a gross of US$32.3 million (KRW32.9 billion).

“Sea Fog” (pictured), a shamanic mystery tale produced by Bong Joon-ho and directed by Shim Sung-bo, showed a less stirring performance. It opened in third slot with 584,000 ticket sales and a box office score of US$4.72 million (KRW4.83 billion), for a cumulative score including previews of 931,000 admissions and US$7.32 million (KRW7.47 billion).

Top scoring Hollywood movie was “Planes: Fire & Rescue.” It opened in fourth slot with a 3% market share of 162,000 ticket sales, for a cumulative 196,000, worth US$1.18 million for the weekend and a cumulative $1.42 million.

“Planes 2” headed off “The Fault In Our Stars” (on a cumulative US$1.78 million after 10 days); “How To Train Your Dragon 2” in sixth place (with a cumulative US$22.9 million since a release on July 23); and “Guardians of the Galaxy 2” in eighth place (and a cumulative score of US$10.1 million since its July 31 outing).

“Roaring Currents” was released in the U.S. on Aug 8, but its director Han-min Kim told the Korean press that he plans to re-edit the film to “better suit international sensibilities.”
