Thoughts on the meaning behind the movie's name
I have recently been listening to Wagner's Das Rheingold, the first instalment of his four part Ring Cycle of operas while reading the important plot points. It is essentially the prologue to the main story and it begins with the dwarf Alberich stealing the Rhinegold which he forges into a magical ring that enables him to take over the world. In exchange, he is forced to give up his abiity to love.
When he is done enslaving his own kingdom, Alberich is set upon by the king of the gods Wotan who wants the ring to give to the giants Fasolt and Fafner in exchange for his sister in law's safety. Alberich places a death curse on Wotan which make every future owner of the ring sure to be killed by the next owner.
In the end of Hideo Nakata's Ring, we learn that the death curse can only be lifted by a copy of the infamous videotape and it being passed on to someone else.
Well I guess they always did say the the Japanese like to pay homage to the Germans (such as in their cars and technology).
