Lee Myung-se was originally attached as the film’s director, then-titled Mister K. In May 2012, production company JK Film (run by CEO/film director Yoon Je-kyoon) filed a copyright lawsuit against Lee, claiming he had “illegally and secretly registered” himself as the film’s copyright holder through the Korea Copyright Commission website after he quit the project in April 2012. The legal battle was sparked after JK Film had a series of conflicts with Lee over the film’s concept. Cineastes and critics had been excited about the rare collaboration between Lee and Yoon ― two influential figures in the Korean film industry who are very different from each other. Yoon is known for his commercial blockbusters Haeundae (2009) and Sector 7 (2011), while Lee is famous for his aesthetically conscious mise-en-scene and style shown in Duelist (2005) and M (2007). However, the producers and Lee had several artistic and creative differences during the early days of shooting in South Korea and Thailand. JK Film alleged that Lee refused to follow the original script, making significant deviations that were no longer appropriate to an action adventure film, and completely ignored every cinematic and stylistic request from the producer: “The film was going to be an action comedy with realistic characters, something like the James Bond series. But director Lee got rid of entire script lines and shot each scene in a rather serene and lyrical way. They weren’t what we initially had in mind as its producers.” JK Film resumed shooting in mid-May 2012, and Lee was replaced by rookie filmmaker Lee Seung-jun (he was assistant director for two of JK Film’s blockbusters Haeundae and Quick).
Director Lee Myung-se and his company, Production M, did not comment.
