Editing Ebirah, Horror of the Deep (section)

===Special effects===
The underwater sequences were filmed on an indoor soundstage where the Godzilla and Ebirah suits were filmed through the glass of a water-filled aquarium, with some scenes of the Godzilla suit shot separately underwater as well. Haruo Nakajima wore a wet suit under the Godzilla suit for every scene that required him to be in the water, which took a week to complete the water scenes, Nakajima stated, "I worked overtime until about eight o'clock every day. I lived in the water! Generally, in the summer, everybody wants to go in the pool and play, but, when it comes to kaiju movies, it is totally different. Most of the scenes that they shoot in the water are not in the summer, but in the winter. In the middle of winter, shooting started at nine in the morning, going until noon, and then we'd take an hour off. But we'd go from 1:00 P.M. until around 5:00 at night. I needed to stay in the water all day in the suit, and shooting took a week."{{citation needed|date=April 2022}}

The Side Monsters that featured in this film were largely dictated by suits and props that were still available from previous films. For example, the [[Mothra]] was the same prop seen in [[Ghidorah, the Three-Headed Monster]] and the giant condor was a repurposed Rodan prop used in flying scenes. Other places where the low budget of the movie can be seen is in the island setting which was picked, as islands are much cheaper to make miniatures of compared to cities. This island trend carries on in other movies such as [[Son of Godzilla]].
