Who or what was "John" in the 2004 film Immortal? He acted as a special consort or guardian of the main character Jill, but what was his purpose for acting as Jill's guardian?
Being such an obscure and foreign film, there aren't a lot of details available. It's also very loosely based off a set of graphic novels by the director, so there is no direct relation to the character in the movie compared to the books.
It would seem that John is just a cosmic benefactor trying to protect and guide Jill through her journey.
