Edo ni arawareta Kingu Kongu: Henge no maki

Sadly recorded as a lost film, it seems highly unlikely that a print of Edo ni arawareta Kingu Kongu still exists even in Japan.

A Japanese version of the RKO classic, it would be especially interesting to see due to the fact Fuminori Ohashi worked on the special effects. He also produced effects for the Godzilla movies, the 60s Toho versions of King Kong (such as Godzilla vs. King Kong) and worked on the original Planet of the Apes.

Considering giant monster movies are one Japan's most famous movie exports - and despite their ephemeral nature, were (and still are) highly entertaining, varied and influential - it's very sad that their earliest ancestor can no longer be seen trampling across the land in all his monotone splendor.
