Trivia[]
- Hasegawa remarked that various tokusatsu franchises most notably Kamen Rider and Ultraman franchises since Heisei era were largely influenced by the Heisei Gamera Trilogy, which was based on a scrapped Gamera script that later became the basis for Ryuta Tasaki's Gamera the Brave and Digimon Tamers and Ultraman Tiga, where various influential practical knowledges and tokusatsu techniques were invented during the production of the trilogy.[1]
