The film tells the story of the fate of the 15th King of Joseon, Gwanghaegun, and the commoner Ha Sun who looks exactly like him. "Gwanghae, the Man Who Became King" tells the story of the 15 days when Gwanghaegun, who was in danger of being poisoned, asked Ha Sun, a poor man who looks exactly like him, to act for him. It is the first film to portray Gwanghaegun, who is evaluated very differently by contemporary and modern people. In the 8th year of Gwanghaegun, the political situation was chaotic and power struggles threatened the king's personal safety at all times. In fear, Gwanghaegun found the chief secretary Heo Gyun and asked him to find a substitute for him in case of an emergency. Heo Gyun found Ha Sun, a commoner who made a living by telling crosstalk, through a drunkard he met at a brothel. He was surprised to find that the man had the same face as Gwanghaegun, and had excellent eloquence and imitation talent, making him the perfect candidate for the king's substitute. So, Heo Gyun took Ha Sun back to the palace, ready to implement the strange plan of replacing the prince with a cat. One day, Gwanghaegun suddenly lost consciousness and fell. Heo Gyun took the opportunity to treat the king and replaced him with Ha Sun, a grassroots from the market, and sent him to the central palace. Under Heo Gyun's guidance, Ha Sun began to imitate the king's tone, walking posture, and made up the current situation of the country and the way to govern the country. But to outsiders, the king has changed unexpectedly from the inside out. The tyrannical and brutal Gwanghaegun is gone, replaced by a kind and warm new emperor. In the process of ruling, Ha Sun gradually made his own voice, which was unexpected for Heo Jun. The charm of the legend behind the scenes "The Two-Faced King" is a historical masterpiece about the fifteenth monarch of the Joseon Dynasty, Gwanghaegun, who wanted to escape the court conspiracy of being poisoned, and exchanged identities with Ha Sun, a civilian who looked like him. The movie will reveal the truth that in the Joseon Dynasty records, the monarch disappeared for 15 days during the 8 years of Gwanghaegun. Gwanghaegun was once considered a tyrant in history, but with further research, it was discovered that many of his actions could actually be seen as reforms and attempts, which were still very positive in the long history. Therefore, bringing the story of such a complex character to the screen naturally attracted the attention of the public, not to mention that it also revealed a blank in the history of the Joseon Dynasty, and it became a focus at the beginning of the filming. Although "I Am the King", which has a similar theme and is starred by Joo Ji-hoon, has been released before, Joo's version is more of an idol card and takes the route of entertainment and humor, while "The King and the Queen" can be seen from the released posters and trailers. This is an absolute historical blockbuster with a large cast, large investment, and large scenes. Of course, the 15 days when Gwanghaegun mysteriously disappeared are mostly folk legends, and have not been accurately verified by history. That is why the story of the raccoon replacing the prince has triggered people's bold associations, and the story of a grassroots person who looks similar impersonating the monarch is the most popular and widely circulated, which is probably related to the fact that it coincides with the daydreams of the general public. The film was written by Huang Zhaoyin, the screenwriter of "Old Boy", and directed by Qiu Changmin. Lee Byung-hun plays two roles. Lee Byung-hun has shown his affectionate and cold temperaments as a man in dramas such as "L.A. Love and Death" and "Iris" and movies such as "I Saw the Devil" and "The Beginning of War". After starring in Hollywood blockbusters "G.I. Joe: The Rise of Cobra" and "G.I. Joe 2", he has become a veritable international star with extraordinary appeal. "The King and the Queen" is his first historical drama. In the film, he plays King Gwanghae and grassroots Ha Sun at the same time, perfectly portraying two very different characters. King Gwanghae gradually loses his judgment in the face of opposition forces on all sides and becomes a tyrant; while Ha Sun is a scumbag, free and enthusiastic. Lee Byung-hun used delicate and stable acting skills to vividly portray the arbitrary and sensitive King Gwanghae and the humorous and kind Ha Sun on the screen. At the press conference, Lee Byung-hun commented on his performance: I was responsible for 80% of the film alone. I had to go into the studio to shoot almost every day. Gwanghaegun is a real historical figure, so the audience has a basic understanding and judgment of him, while the role of Ha Sun is fictional. In addition to the content provided by the script, there is a large part that I need to digest and interpret myself. Therefore, when playing a silly character like Ha Sun, I also began to try to unleash my potential for comedy, and I was surprisingly satisfied.
