Having been offered a small budget to make two films, director Kiyoshi Kurosawa and writer Hiroshi Takahashi each hastily wrote scripts. Both were versions of the same basic premise: a father seeks vengeance. Hiroshi Takahashi wrote Serpent's Path (1998) and Kiyoshi Kurosawa wrote Eyes of the Spider (1998) with the collaboration of Yôichi Nishiyama , and Kiyoshi Kurosawa ended up directing both films.
Production of this two part project took 1 month. Both films were shot back to back with the same cast and crew.
