Directors Shin-yeon Won and Gong Yoo, both of whom are born in martial arts, are grateful for the achievement of this once-in-a-lifetime collaboration opportunity. The two show a high-profile Hollywood-style production project with the background of Seoul, Hong Kong, China, and Latin American countries. The latest Hollywood equipment is used for high-altitude full monitoring to perform large-scale car chase scenes. In particular, Gong Yoo reborn as a boxing expert, showing in the movie a martial arts action called "systema" used by the former Soviet Union spy members, which can kill the enemy. The setting of the best killer weapon among the Korean soldiers is impressive. expect.
The film also uses the special facilities of the Busan Film Studio in Haeundae, Busan, and the first-ever Digital Bay filming system in Asia. The actors face the green set to perform most of the scenes, which is a great challenge to acting.
The film again involves the issue of "North and South", but this time there is no political advancement, and everything serves the "good story". The film’s location not only featured local landmarks such as the Han River, but also staged a land, sea and air battle, and was filmed in Hong Kong, Puerto Rico, and other places. The dim back alleys of Hong Kong, the harbor seen from the skyscrapers, and the beautiful scenery of Puerto Rico all inject exoticism into the film, creating a sense of drifting beauty beyond the hot and exciting rhythm.
