I first encountered Itao Itsuji (板尾 創路) while watching Gaki no Tsukai batsu games. He is a Japanese comedian well known for having a very odd sense of humor and the guys at Gaki no Tsukai love to showcase it. He is also an actor and has appeared in over 20 films including Tokyo Gore Police and Love Exposure. I suspect his choice in film roles is influenced by his sense of humor. His latest role comes in the movie Air Doll and when I first heard about the film I visited YouTube to find out more.
The trailer didn’t offer much insight, but I tracked down a copy of the film and watched it.
