Song Joong Ki expressed his feelings about his new movie, "Wolf Boy". He had no lines in the movie but he had to act with his facial expressions and body language/movement. He said that it was actually very uncomfortable. During the press conference held on October 15th  with director Jo Sung Hee along with the cast Song Joong Ki, Park Bo Young, Jang Young Nam and Yoo Yeon Suk; he expressed his feelings about the situation.

"Having no lines... I thought it would be easy, but it's actually very difficult," he continued, "It's like a soldier without a gun,"

He also mentioned another uncomfortable hurdle during the movie, "Walking on all fours was uncomfortable at first, but then I remembered I had no lines and I had to listen to Park Bo Young's lines,"

"Wolf Boy" is a love story about a wolf-like boy and a lonely girl who isn't really involved with the world. Song Joong Ki actually has 10 lines in the whole entire movie. He mostly growls and does animal-like movements throughout the movie.
