Gone but not forgotten: Haruo Nakajima, the actor who played movie monster Godzilla over two decades of Japanese cinema, died Monday at 88

Speaking with Great Big Story in March, he revealed that the reason the heavy concrete was used instead of rubber was because of a shortage of the latter stemming from World War II.

'It was so heavy and hot, and with the lighting, it was even hot to touch it,' he told Great Big Story. 'I was sweating all over my face, but I did the best I could.'

He said he visited the zoo in Tokyo to get a feel for how to move around like the monster by observing 'big animals, like elephants and gorillas.'
