The original script was a comedy. Takeshi Kitano was then very concerned about the audience recognizing his acting skills and he didn't feel that a comedy would allow him to act nor allow the audience to abstract from his comic TV personality. So he rewrote the script, removed all comedy and turned it into a drama.
Cinema, short for cinematography, is often used to refer to the industry of films and filmmaking or to the art of filmmaking itself. The contemporary definition of cinema is the art of simulating experiences to communicate ideas, stories, perceptions, feelings, beauty or atmosphere.
