Song Seung Heon, who recently played Han Tae Sang the loan shark turned businessman in the drama "When A Man Loves," is considering his next project and this time it's an adult-rated film.

The film, "Human Addiction," is the story of a war hero and a general. Song Seung Heon is reading the script with the idea of playing the general, a man of principles.

That character's principles will be tested when he falls in love with a woman who is married to one of his men. The film is set in the late 1960s.

The film's director and scriptwriter is Kim Dae Woo, whose screenplays include "An Affair," "The Foul King" and "Untold Scandal." Kim wrote and direct directed "The Servant" and "Forbidden Quest." Common themes in his works are social taboos and he won Best New Director and Best Scriptwriter for "Forbidden Quest."

Song Seung Heon's long career has included playing many types of characters but this would be his first adult-rated film. His career started with the popular drama "Autumn in My Heart," after which he played in the romantic "Summer Scent" with Son Ye Jin.

The actor has said that while he is grateful for his good looks, they have limited him in terms of acting.

"People kept seeing my looks first," said Song, when he was accused of not being a realistic gangster type in "When A Man Loves." "But I think it's up to me to make the effort and take up new challenges."

He tried more masculine roles in "East of Eden," "Fate" and "A Better Tomorrow." Then he returned to sensitive and romantic with the Japanese film version of "Ghost."

At one point he was called the "King of the Melodramas."

"After my discharge from the military, I played some so-called rough male characters because I wanted to change as an actor," said Song. "I wanted to change people's image of me as a gentle and considerate guy and felt some hostility toward the pretty boy image."

And yet he thoroughly enjoyed his first romantic comedy "My Princess" with Kim Tae Hee.

"Previously, I took on characters whose lives were complicated with ups and downs," said Song of his "My Princess" role. "Hae-young was the first role I played that was so rich, bright and cheerful. I felt much lighter while acting the character."

In the same year that he played the seemingly cold-hearted but secretly romantic Han Tae Sang, he filmed the historical film, "The Messenger." He read the script in one sitting and thought the action scenes sounded thrilling.

As to "Human Addiction?" He's considering this new direction in his career.
