Anime News Network wrote:Kadokawa announced on Thursday that it has green-lit a movie titled Sadako vs. Kayako, which will bring together the iconic horror film characters Sadako from Kadokawa's Ring franchise and Kayako from NBCUniversal's Ju-on franchise. The film will star Mizuki Yamamoto, and is slated to open in June 2016. Kōji Shiraishi (The Curse, A Record of Sweet Murder) is directing the film. Kadokawa also began streaming a teaser for the film on Thursday. Yamamoto (Hunter × Hunter -The Last Mission-, live-action Daily Lives of High School Boys) will play the character Yūri Kurahashi, who is caught between Sadako and Kayako. This will be Yamamoto's first horror film, but she stated that she is a fan of horror films, especially Shiraishi's The Curse. Yamamoto commented that her character Yūri has a strong sense of justice. The website of Ju-on: The Final previously ran an April Fools joke on its website that promoted a then non-existant "Sadako vs. Kayako" crossover film.
