How did they make the Godzilla costume glow?
Godzilla was originally going to be luminescent red and white, but it didn’t look right. Instead, they had hundreds of tiny orange light bulbs and put vinyl plates over them. The lights were powered by a huge electric cable running out the tail. The steam was achieved using a “carbonic-acid” gas. Not only did this illustrate Godzilla’s suffering, but Kenpachiro Satsuma suffered as the man in the suit. At times he’d accidently inhale the gas and faint. Other times, the lights and cables electrocuted him in water scenes. By the way, except the lights and steam, Godzilla’s suit in this movie (Desu-Goji) was the same one used in vs SpaceGodzilla (Moge-Goji).
