The remake is really really confusing its a shot for shot remake of ju-on by the same director and proudced by Sam Raimi and a small part is being played by Ted Raimi. There is ALSO a rerelease of Ju-on The grudge (the remake is called the grudge) so if you are lucky enough to live in a city where they are playing it go see it.
imdb has some info

also apples website has both trailers for the rerelease and the remake... should be an interesting summer
