While the US BD of Hellraiser 3 is not avaible, yet, as far as I know, the japanese BD Box set with the first 3 movies is.
I hope that the US will get a new transfer of Hellraiser 3 movie, and not, as the Hellraiser 1 BD, a more filtered one than japan.
Additionally: Hellraiser 3 jap. BD is just 93 min. running time: that point towards the r-rated Version.
To be honest: the japanese Bd of Hellraiser 3 is not worth to buy:
comparison: ger DVD vs. jp. BD
Oh, and why I mentioned that the US BD of Hellraiser 1 is a bit more filtered:
The jap. BD instead has some scratches which where filtered away in the US release...
