 Haruo Nakajima (qv) could walk about thirty feet in the original  costume, which weighed over 200 pounds (91 kilograms). Later  costumes were a little lighter but all of the costumes were very  heavy. It was also very hot inside the costume. All of the costumes  after the first one were easy to work with, as they were made to fit  Nakajima, whereas the one that had been built for Godzilla had not  been made for his body size.
