It's like Freddy vs. Jason except, you know, scary.
Of all the J-horror films to come out in the past fifteen years (of which there have been many), Ringu and Ju-On are easily the most well-known in both their native country and here in the States, thanks in no small part to the hugely successful American remakes they spawned -- The Ring and The Grudge, respectively. In fact, the American Ring franchise is still running strong to this day, with a third entry in the series, Rings, set to be released in October.
Likewise, with the final Ju-On film having been released in Japan over the summer (and a Sam Raimi-produced American re-remake of the original The Grudge currently in production), it's obvious that both franchises still carry a lot of fan interest. So when a fan-made trailer mashing up the two J-horror staples went viral on April Fool's Day, the folks at Kadokawa and NBCUniversal Japan knew that they only had one place to go with the series': a Freddy vs. Jason-style showdown of epic proportions.
As such, the two media conglomerates announced back in December that they would be joining forces to deliver the ultimate battle of in The Ring vs. The Grudge.
Sadako vs. Kayako (as it's being billed in Japan) revolves around "a girl, Yuri Kurahashi, after watching a cursed videotape with her friend, becomes trapped in a conflict between Sadako Yamamura and Kayako Saeki" -- Yamamura of course being the central character from the Ringu series and Saeki from Ju-On.
A teaser trailer for Sadako vs. Kayako hit the Interwebs earlier today, and suffice it to say, you might not make it all the way through without needing a clean pair of shorts. The original Ringu and Ju-On may have been praised for their restraint, but personally, I'm all for the idea of seeing both ghosts throw subtlety out the window and throw down in a good old fashioned, American-style battle of egos. Anyone else onboard?
Sadako vs. Kayako scheduled for release in 4-D next June in Japan.
