The two titanic franchises of the Japanese supernatural horror genre – “The Ring” and “The Grudge” – are coming together in a “Freddy vs. Jason” style mashup. The first trailer is out today for “Sadako vs. Kayako,” a revival of both franchise by Kadokawa Productions and NBC/Universal in which the ghosts from both “Ringu” and “Ju-On” take on each other with a human girl named Yuri caught in the middle.
The project was reportedly inspired by a fan-made teaser cutting together footage in a way to suggest the idea of such a project. That teaser became a viral sensation in Japan and so an actual film was born. No word on a U.S. release at this time.
