D-War, directed by Korean director Shim Hyung-Rae, was released in South Korea and the US in 2007. D-War’s (poor) plot revolves around Korean mythology, but is set in modern Los Angeles, with a cast that mainly consists of Western actors.
So, is D-War a Korean or US film, if it attempts to portray parts of Korean culture/mythology in the US, and with a US cast?
