The next film in the Ring, or perhaps more properly Ringu, series is Sadako 3D. Not only is Lady Longlocks back from her special hidey hole, there's more videotape shenanigans, more young people in peril and another secret way to get rid of evil
forever if only our heroine can figure it out in time.
Here's the first teaser, apparently released a couple of days back in Japan. I've now been sent this official embed.
The film gets a home release in May, though I'm pretty sure this one will travel, and before long. This chapter was directed by Tsutomu Hanabusa, a newcomer to the series.
