A South Korean film about the Korean War ranked 27th at the U.S. box office after the first two days of its release, data showed.

"Operation Chromite," a story about the 1950 landing operation led by U.S. Gen. Douglas MacArthur, grossed $189,945 until Saturday since it was released in 114 theaters on Friday, according to data from box office data firm Rentrak.

Until Friday, the film had been shown only at the CGV LA theater since Aug. 5. Combined with the sales at the theater, the movie earned a total of $251,928.

The film's distributor, CJ Entertainment America, said the film will be screened at 24 more theaters.

Starring Lee Jung-jae, Lee Bum-soo and Hollywood star Liam Neeson, the historical action flick tells the story of real-life South Korean soldiers who carried out a covert operation to prepare for the daring amphibious landing led by MacArthur.
