Park Yoo Chun of the K-pop trio JYJ announced on Monday will be appearing in his first feature film, Bong Joon Ho's "Sea Mist."

The singer made the announcement through a post on the official JYJ Naver Line online account, where he promised he would give the role everything he has.

"I really thought this over a lot," the JYJ singer wrote. "I'll work hard on the new piece and learn more...you'll still have to wait longer, but I will make sure to repay you with great acting. Thanks everyone! I believe that the only way to repay your trust is to do my best with a sincere heart in my role."

The plot of "Sea Mist" revolves around several sailors on a smuggling ship, according to the publication eNEWS.

A representative from JYJ's record label C-JeS Entertainment asked fans to support Yoo Chun's decision to appear in Bong's film, despite the fact that it could take time away from his band activities.

"Like he revealed through Line, Park Yoo Chun has recently decided to appear in 'Sea Mist,'" said the record label rep. "We hope to see your support for his first big screen piece."

An acclaimed director and screenwriter, Bong's most recent films include 2006's "The Host," 2009's "Mother" and the film "Snowpiercer," currently in theaters

In 2008 he collaborated with Michel Gondry and Leos Carax to direct the cinematic triptych "Tokyo!" in which each director took on a section of the film.  

Bong has won three Asian Film Awards; Best Screenplay and Best Film for "Mother" and Best Film for "The Host," along with four Korean Film Awards; Best Film, Best Director, Best Screenplay for the 2003 film Memories of Murder and Best Director for "The Host."

He has also served as a jury member for the Sundance Film Festival and the Cannes Film Festival.

A post-apocalyptic thriller, Bong's "Snowpiercer," has been breaking box office records in South Korea.

The director's first offering in English features star of HBO's "The Newsroom" Alison Pill as a creepy cartoonish school teacher with a wardrobe reminiscent of "Alice In Wonderland."

Last month, "Variety" Chief Film Critic Scott Foundas praised the "Snowpiercer" for its independent spirit.

"By the end, the film reveals itself as a surprisingly thoughtful contemplation of man's inhumanity to his fellow man, and whether mankind is worth trying to save at all," Foundas wrote.

"Somber stuff, to be sure, but not without flashes of hope, and a steady infusion of Bong's dark, quirky humor."
