The fight choreographer for the film was Taku Sakaguchi who Nishimura has worked with previously on the film "Meatball Machine". The comical yet satirical television commercial scenes in the film were filmed by Noboru Iguchi and Yūdai Yamaguchi. Yamaguchi suggested this to bring a different flavor to the film to balance out the rest of the film's more dark tone.
