dark water

Now I'm watching the Japanese version. There are several allusions to Sadako (from Ringu) in it: the ghost of the dead girl walks by the doorway and looks just like the young Sadako in the flashbacks to when Sadako's mother was doing a psychic demonstration for the press. Then when the girl first approaches the alive little girl, you only see a pair of white stockinged legs and shoes, similar to the legs that appear in front of Ryuji (that part wasn't in the book, though).

Also, in the American version of Dark Water, there are some homages to the Japanese Ringu--the most notable one is the kind of filming that occurs when Jennifer Connelly's character climbs up the water tank. The footage flashes back and forth between her and the past, when the little girl (Natasha) climbed up and drowned. Also, there are shots from inside the tank, looking up, similar to the ones in Ringu (with Sadako at the bottom of the well).
