We know for a fact that Crown Prince Sado of Joseon died in a rice chest. So, what is the story behind this fact? During the movie’s production press conference, Song Kang-ho, who plays King Yeong-jo, said that more than 90% of the movie’s content was based on facts. Director Lee Joon-ik’s movie depicts the tragic family history hidden behind the well-known death of the prince. He follows the heart of the father who had no choice but to kill his own son by locking him in a rice chest. In this movie you get to witness King Yeongjo in his 40s to 80s through Song Kang-ho, who reportedly used a special voice only for this role. Yoo Ah-in plays the part of the tragic crown prince. We look forward to hearing more about how Lee Joon-ik, who produced and directed historical movies such as Once Upon a Time in the Battlefield and King and the Clown, directed this movie.
