South Korean singer-actor Seo In Guk will be playing the role of a prince in the upcoming period drama "The King's Face."

In Guk will be playing Prince Gwanghee, who is a prince who gets to escape from numerous death threats. According to KdramaStars, it will be his first time starring in a historical drama or "saeguk" in Korean language.

His character, Prince Gwanghee, has already been portrayed by other actors such as Ji Sung, Lee Byung Hun and Lee Sang Yoon. Seo In Guk said he is taking the challenge to make the iconic role his own.

KdramaStars added that In an interview, the actor said, "The character of Gwanghee has been portrayed very well by many senior actors so while I am glad to take on this role, I also feel some pressure."

"I'll work hard on acting and show you Seo In Guk's own Gwanghee," he added.

Meanwhile, Seo will be working with actor Lee Sung Jae, who will play his father, King Seongio. Seo and Lee have worked together in "Rascal Sons" where they played as brothers.

"I gain even more strength in knowing that I will be acting in my second project with Lee Sung Jae whom I have always been friendly with," said Seo.

Moreover, the drama was involved in a legal dispute with Jupiter Film, which produced the 2013 film "The Face Reader," over an issue of plagiarism, Kpop Herald reports. The film company filed in August a provisional injunction action against KBS 2TV over what they claim as intellectual property rights violation.

Jupiter Film argued that they have met with their KBS counterparts to talk about the TV series version of the work, but the two parties did not reach a deal. The film producer also claimed that they gave the script along with a printed proposal on the drama version for the network to review.

They are claiming that KBS' "The King's Face" shares similar plot features and characteristics that cannot be deemed as merely incidental.

Last month, KBS stated, "We will not idly watch a movie production company representative spread false information intentionally. We are planning on dealing with them sternly and under the law."
