Kim Seong-Yoon, the director of the Netflix series “The Sound of Magic,” talked about how he chose the three main actors, Ji Chang-Wook, Choi Sung-Eun, and Hwang In-Yeop.
The director recalled asking Ji Chang-Wook to play the role of Lee Eul. “It’s a role that requires a lot of work,” he said. “Lee Eul is a character who does not appear frequently in the drama, but he must impress the audience each time he does. The actor had to perform magic, sing songs, and do choreography to play him.“
“He is an actor who enjoys the challenge and works hard,” director Kim said of Ji Chang-Wook. “I was surprised by his passion, and I gained energy from him while filming,” he added.
Because the drama is based on a webtoon, some drama fans have mentioned that Ji Chang-Wook in the drama resembles Lee Eul in the original work. “When casting the actors, appearance appears to be secondary,” the director said of the casting process. “More importantly, the actor’s own charm and the character in the script must be well-balanced.”
The director stated that he watched the film “Start-Up” before casting Choi Sung-Eun in the role of Yoon Ah-Yi. “I thought Yoon Ah-Yi is the character who leads the drama flow, so I wondered which actress would fit the role,” the director explained. “I was intrigued by Choi Sung-Eun after seeing ‘Start-Up,’ so I interviewed her twice. I discovered that she is the one who possesses the sadness that Yoon Ah-Yi has. She’s also a talented actress.”
Director Kim mentioned that Choi Sung-Eun was concerned about the singing part. “I told her I would have cast an idol or a musical actress if only to produce a music drama or musical drama,” the director explained. He further said, “The reason I cast Choi Sung-Eun, who had no singing experience, is that the emotional line is what leads the drama flow. The songs are additional elements to convey those emotions.”
Before the release of “The Sound of Magic,” some questioned whether Hwang In-Yeop, who is in his 30s, could play a high school student, Na Il-Deung. The director stated that he had no idea how old Hwang In-Yeop was. “The actors can wear different clothes regardless of their ages, so that’s not an important part,” he explained.
He said of Hwang In-Yeop, “He has cuter and more attractive characteristics than someone who pretends to be cold, arrogant, or strong.” “I believe the characteristics of him and Na Il-Deung were well blended as he acted as Na Il-Deung.”
