The creation behind Godzilla is actually a lot simpler than you’d expect. They used an actor wearing the Godzilla suit, and placed miniature buildings around him. Keep in mind, though, that the original film was released in 1954, way before the striking technological development of our days.
It wasn’t as simple for the actor of Godzilla, though, who had to wear a suit weighing 20,000 tons, made of wires, bamboos, fabric, cushion and latex – who came up with the idea for this suit?!
