I'm down a new Kiyoshi Kurosawa rabbit hole. Here's the short version of this interesting trio of connected movies:
Fresh off dropping Cure (imo, the best Kurosawa movie), Kiyoshi Kurosawa got an offer to make two movies on a low budget. So he grabs Hiyoshi Takahashi, the screenwriter of Ringu, and they come up with a shared premise. Basically, "a father seeks revenge for the murder of his daughter" and the two writers each write their own script.
They used the same teams and shot both films in a month. Takashi's script became Serpent's Path; Kurosawa's script became Eyes of the Spider. Kurosawa directs both, and they were made smack in the middle of his run that started with Cure and culminated with Pulse. Now, Serpent's Path gets a lot of love as a cult classic so much so that Kurosawa remade it in France last year.
So, these are on my "watch ASAP" list now.
