CEO Yuichi Nagano is impressed and approves it, although director Mitsuo Muraoka points out that one of their competitors just released its own kaiju movie.

Tsukaji and Yukawa, tasked with deciding what kind of monster should star in the film, visit a zoo in Tokyo.

The film's actors, including Utsumi, Michiko Ogata, Junko Kamei, and Schmidt, assemble for a table-read.

Screenwriter Hasebe's story features the United States and the Soviet Union announcing a joint lunar expedition.

Citizens living near the studio interrupt the shoot on October 25 in protest, concerned about the rats spreading disease.

On November 3, Daiei receives a stern letter from the Bureau of Social Welfare and Public Health recommending the termination of the film and the rats.

After Tsukaji immolates the rats the following day, he stands silently amidst one of the sets, then crushes one of the buildings in a fit of rage.

Yukawa reflects in his documentary that even though Giant Horde Beast Nezura was a failure, it taught him a lot about filmmaking.

The film's production was shut down by the health department because the wild brown rats used were escaping the set and had the potential to transmit disease to the surrounding area.
