Nezura 1964 Plot Explained: Your Questions Answered

The questions people ask most about Nezura 1964 (2020): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why did the filmmakers decide to use rats for the monster design?

After visiting the Tokyo Zoo failed to inspire a creature concept, CEO Yuichi Nagano suggested using a mundane animal after watching a bird film. Tsukaji and Yuichi settled on rats because they were readily available and could be filmed in large numbers, making them practical for depicting a horde of monsters.

Q2

What led to Giant Horde Beast Nezura being cancelled?

The production faced multiple crises: citizens near the studio protested over disease concerns from the rats, the Bureau of Social Welfare and Public Health sent a letter recommending termination, and on-set chaos with fleas and disease forced crew members to wear masks. These public health and safety issues made the project untenable.

Foreshadowing: Earlier protests had been brewing as local residents grew concerned about disease transmission from the rat colony.

Q3

How is Nezura connected to the Gamera franchise?

Giant Horde Beast Nezura was a failed Daiei production that served as an early precursor to Gamera. After the project was cancelled, assistant director Kazuaki Yukawa visited CEO Yuichi Nagano on January 3 and saw a spinning firework that inspired a new monster concept, which was rushed into development and eventually became Gamera.

Q4

Why did local residents protest the film's production?

Citizens living near Daiei Studios protested on October 25, 1963, fearing the large rat colony gathered for filming would spread disease throughout the neighborhood. Their concerns proved valid when fleas and illness began affecting the production crew.

Foreshadowing: The decision to collect rats from the public and fill a warehouse with them had raised early alarms.

Q5

What role did the Bureau of Social Welfare and Public Health play in the film's fate?

On November 3, 1963, the Bureau of Social Welfare and Public Health sent a stern letter to Daiei recommending the film's termination. This official government intervention, combined with the local protests, effectively ended any chance of completing the production.

Q6

Why did the production switch from domesticated rats to wild rats?

The initial test footage filmed with domesticated rats proved troublesome because the animals were hard to control on set. Special effects director Yonejiro Tsukaji traveled to downtown Tokyo to capture wild rats, which filmed more successfully and convincingly for the monster sequences.

Q7

What was the Mammoth Nezura puppet used for in the film?

The Mammoth Nezura was a large puppet built by Daiei staff for on-screen action sequences. It was featured in battle scenes alongside the smaller rat creatures, with JSDF forces attempting to contain the monster threat during the fictional rampage through Tokyo.

Q8

What inspired the new monster concept at the end of the film?

On January 3, after the project's failure, Yukawa visited Nagano's home where he observed a spinning firework. This visual inspired a new monster idea that they rushed back to Daiei to develop, which ultimately became the basis for Gamera.

Q9

What space-themed elements were in the script?
