In 2008 Toho Studios produced the documentary
Bringing Godzilla Down to Size: The Art of Japanese Special Effects.
Directed by Godzilla junkie Norman England, the documentary tells the entire story of an amazing era of Japanese SFX, begun by Eiji Tsuburaya and Yasuyuki Inoue.
Bringing Godzilla Down to Size is included on the DVD release of
Rodan/War of the Gargantuas by Classic Media.
While it’s odd to find a doc about
Godzilla with movies in which he makes no appearance, it is beautifully done. Narrated by Alex Cox, the doc contains plenty of interviews, including with Inoue and the members of his amazing crew.
