Trivia: This film, despite being marketed as a sequel to the "Ringu" film series, is actually more a sequel to the non-canonical "forgotten" sequel "Rasen" than it is to the original "Ringu" or its follow-ups "Ringu 2" and "Ringu 0: Birthday."
Trivia: Had the biggest time gap between films in the "Ringu" series - it was released 12 full years after the previous film - "Ringu 0: Birthday." The prior four "Ringu" films were released a year or less apart throughout the late 90's through the year 2000.
