The film was present by Younggu Art Movies which was established by Shim as Yonggary, but the quality of the computer graphics had increased a lot (Although it is not really well as the Hollywood movies), especially the design of Imoogi, it had been charged few time while designing.
The main antagonist and monster of another of Shim's Korean monster movies in this film is Buraki, a Imoogi bent on destroying the world.
Shim took the film in L.A., and most of the cast are actors in Hollywood (Although most of them are not famous), and Hollywood filmmakers, that's why this film cost him about 30 billion won ($32 million U.S. dollar).
Based on the Korean legend, unknown creatures will return and devastate the planet. Reporter Ethan Kendrick is called in to investigate the matter, and he arrives at the conclusion that a girl, stricken with a mysterious illness, named Sarah is suppose to help him. The Imoogi makes its way to Los Angeles, wreaking havoc and destruction. With the entire city under arms, will Ethan and Sarah make it in time to save the people of Los Angeles?
In accordance with a Korean legend, every five hundred years, a woman protected by a man transforms in a serpent to fight against a dragon in a battle between good and evil. In Los Angeles of the present days, after a mysterious accident, the reporter Ethan Kendrick recalls his meeting fifteen years ago with Jack, who owned an antique shop and told him that he was the one supposed to protect Sarah Daniels. Ethan seeks out Sarah and together they fight to survive and destroy the devilish dragon.
Originally titled Dragon Wars (and still referred to by this title in publicity material), D-War has a long production history in South Korea. The film was announced in 2002 by director Shim Hyung-rae as his follow-up project to 1999'sYonggary. A show reel appeared in early 2003, showcasing the extensive amount of CGI the production would be using to create the various creatures. Despite heavy promotion via posters, press releases and videos, principal photography did not begin until October 2004, continuing through December. The budget was set at approximately $33 million (30 billion won), but ultimately went over budget in order to create the various creatures in the film, with some outside estimates as high as $75 million dollars. As with Yonggary, Shim opted for a mostly American cast. Veteran actor Robert Forster landed a pivotal role and Jason Behr and Amanda Brooks were cast as the two young leads. The next three years were spent creating the creature effects, all of which were done in house by Shim's Younggu-Art Movies company. The completed film premiered at the American Film Market in early 2007. The film was released in South Korea on August 1, 2007. In the U.S., the film was released on September 14, 2007. On August 7, 2007, South Korea's MBC Morning Live TV Show broadcast the film's final scene on TV without the permission of the studio, causing a controversy. A few days later the Ministry of Culture and Tourism released a statement in which they said that the incident did not violate South Korean copyright laws.
