Godzilla's roar has long been considered one of cinema's most iconic and recognizable sounds. Oft-copied or otherwise homaged, the original and rather unique roar terrified audience goers in the 1950s and has been built upon to dramatic effect in the numerous sequels and remakes since. So how did they actually make the original sound and where did the idea for Godzilla come from in the first place?
As for the idea behind the monster, producer Tomoyuki Tanaka was looking for a project to work on after another film he was involved with got scrapped. Given the popularity of such films as King Kong among Japanese audiences, he decided to create a similarly themed movie. Except in this case, the monster would function as a not so subtle metaphor for the devastation of nuclear destruction and its radioactive aftermath ‚ hence Godzilla being a prehistoric creature awakened and energized by atomic explosions, and who in turn shoots a radioactive heat beam out of its mouth, leaving a wake of death and destruction, with many survivors in turn suffering from radiation sickness.
