Song Joong Ki expressed his feelings about his minimal lines in "Wolf Boy".

In a press conference held on October 15th for the new movie, "Wolf Boy" starring Song Joong Ki, Park Bo Young, Yoo Yeon Suk and Jang Young Nam. The actor talked about a new challenge he took. He only had 10 words in the entire movie.

He states that "It was really heard to act with no lines, at first I thought it was easy, but it was harder than I thought. I had to act on actions only. It was like a soldier without a gun"

He continued on, saying, "walking on all fours was really hard and uncomfortable, but I thought I only had to act while listening to Bo Young. Then I realized I had to act without my co-workers around. I shared my experience with a senior actor and he told me that listening to my co-actor was basic. This movie taught me a lot."

The movie that will be out on October 31st is about the love story between a werewolf boy and a loner girl that decided to give up on the world.
