What is The Crowned Clown about? From Wikipedia:
The story takes place at a time in Joseon history, when upheaval and power struggles surrounding the throne had reached extreme levels. In order to escape those who plan to assassinate him, the king puts a clown, who looks exactly like him, on the throne.
I see. A king puts his lookalike on the throne to take any bullet meant for him. How courageous. But of course, all good stories are about growth and discovery and the clown will probably start to take the job seriously while hiding his true identity. It’s based on 2012 box office success Masquerade.
It stars Yeo Jin Goo (Reunited Worlds) in the dual roles of Ha Sun and Lee Hun and Lee Se Young (A Korean Odyssey) as Queen Yoo So Woon who will likely be caught between her husband and his doppelganger.
The Crowned Clown premieres on January 7th on tvN.
