Violence in Korean High School, especially inside the WaSanGo (Volcano High). You won't be able to escape.
The Korean, Japanese and US versions have different soundtracks. First two have rock music, the US edition done by MTV has hip hop artists.
MTV productions and infamous studio Distant Horizons produced an English dub of this movie in which all of the voices are dubbed by American rap stars (including Snoop Dogg and Method Man). This version contains heavy amounts of alterations. It contains an entirely revamped storyline that was created with completely new dialog (that bears no resemblance to the original dialog), totally reshuffled scenes, and around 40 minutes cut out.
