Noboru Iguchi
Yamaguchi's September 2006 film "Meatball Machine", which he co-directed with Jun'ichi Yamamoto based on an earlier film by Yamamoto, has aliens taking over human bodies and turning them into bio-mechanical monsters. In August 2008, Yamaguchi released "", a horror story about a monster-baby which is a more subdued work than his previous manic comedy efforts. Along with Noboru Iguchi, Yamaguchi directed the fake TV commercials for good friend Yoshihiro Nishimura's cult horror film "Tokyo Gore Police" after Yamaguchi suggested that it might balance out the dark tone of the movie.
