* KeepCirculatingTheTapes: Licensed by Creator/MediaBlasters, but the DVD is now out of print.
* LoopingLines: The late Eiji Maruyama looped Hideyo Amamoto's lines as Dr. Shinigami.
* ScienceMarchesOn: The film makes repeated references to a famous experiment involving ice crystals that has since been discredited (and most serious scientists thought was a bunch of NewAge-y hippy crap from the get-go, anyway). In their defence, the film is just being poetic about it.
