Japanese film Ichi The Killer has dominated these kinds of lists for years. The violence of Itchi is so intense, so gruesome, that it often borders on comical, or cartoon-like. Whether it's a boiling pan of oil being thrown on someone's back, the rape and beating of a prostitute while someone masturbates, or metal skewers shoved through the side of the face, this movie is seriously revolting. The story begins when Yakuza boss Anjo disappears. A sadomasochistic man named Kakihara and the rest of his mob goons go looking for him. After capturing and torturing a rival Yakuza member looking for answers, they soon realise they have the wrong man and begin looking for the man named Jijii who tipped them off in the first place. Kakihara and his men encounter Ichi, a psychotic, sexually-repressed young man with amazing martial arts abilities and blades that come out of his shoes. One by one Ichi takes out members of the Yakuza, and boy is it violent.
