Wolfman vs. Godzilla (partially found footage from unfinished fan film; 1981)
Densetsu-no Kyoju Ookami Otoko tai Gojira (Wolfman, the Legendary Colossal Beast vs. Godzilla), colloquially known as Wolfman vs. Godzilla, is a fan-produced tokusatsu kaiju film from 1981 that was shot on Super 8mm.
The project began in 1979 when director Shizuo Nakajima and his crew produced a 36-minute effects reel featuring Godzilla, a giant Wolfman, and Baragon from Frankenstein Conquers the World (1965). The Godzilla costume was based on the one from Mothra vs. Godzilla (1964).
Inspired by the werewolf effects in The Howling (1981) and An American Werewolf in London (1981), Nakajima and Fuyuki Shinada made a newer, impressive-looking Wolfman costume and a re-creation of the “King-Goji” suit from King Kong vs. Godzilla (1962). It has been said that a majority of the people who worked on the film were employed at Toho Studios and would go on to do effects work for numerous features.
Due to a variety of circumstances, the project was never completed. Nakajima compiled some of his footage in the form of a three-and-a-half-minute trailer that ended up being occasionally screened at a variety of film festivals, including a screening at G-Fest XIX in 2012. More recently, a much longer 28-minute preview has been put together by Nakajima and shown in at least one film festival. Other than these, it's unknown if or when the film will ever be released, although Nakajima has reportedly been trying to get it released.
Although a final cut has not been released, 26 minutes of effects footage was put onto the Internet Archive on July 3rd, 2021, by user Kaiju No. 14.
