On September 6, writer Kim Eun Sook attended a talk show with Signal writer Kim Eun Hee.
She shared stories about her casting process, commenting, I also get rejected so much, so when an actor eventually comes to me, I become crazy in love with that actor as the character. I sincerely only think of that actor, whether male or female. Once the drama is over, I hope for their continued success and for them to shoot lots of advertisements.
The MC followed up by asking which actor has rejected her the most, to which she responded, Gong Yoo is the actor that has rejected me the most. However, after trying persistently over and over again, I came to work with him for Goblin. Looking at scenes that were filmed, I felt so proud. He is that great of an actor.
Kim Eun Sook has written several hit dramas including Goblin, Descendants of the Sun, Heirs, Secret Garden, and A Gentlemans Dignity. Her next project is Mr. Sunshine, which will star Lee Byung Hun, Kim Tae Ri, Yoo Yeon Seok, and Byun Yo Han.
