JYJ's member, Kim Jae Joong revealed a dangerous episode, while he was filming for a movie.

On the 16th of October, Kim Jae Joong went to the press conference for 'Code Name: Jackal,' that was held in Hannam-dong, Yongsan-gu, Seoul Blue Square Samsung Electronics Hall.

Kim Jae Joong and Song Ji Hyo chose the keyword of the movie to be a 'sword.' Song Ji Hyo said, "I'm usually clumsy, so as I was using the sword, I dropped it on Kim Ja Joong. In the movie, I'm a killer, but a character that's very clumsy. It never ended on a perfect note."

Kim Jae Joong said, "there's a scene where Song Ji Hyo is playing with the sword and has to drop it between my legs. Honestly, I was scared of Song Ji Hyo who was playing with the sword, but it was okay, since she practiced a lot," and he made people laugh.

Meanwhile, in the movie, 'Code Name: Jackal,' the legendary killer Bong Min Jung(Song Ji Hyo) kidnaps the greatest top star, Choi Hyun(Kim Jae Joong). The movie is to be released in November.
