The co-writer said that the film will focus on the iconic monster as an allegory for the "terrifying force of nature".
"What I found very interesting about Godzilla is that he started off definitely as a metaphor for Hiroshima and Nagasaki," he told io9.
"And some of the atom bomb testing we were doing in the South Pacific in the subsequent years. The giant terrifying force of nature that comes and stomps the s**t out of your city, that was Godzilla.
"What we're trying to do with the new movie is not have it camp, not have it be campy. We're kind of taking a cool new look at it. But with a lot of tradition in the first film. We want this to be a terrifying force of nature.
"And what was really cool, for me, is there was a very compelling human drama that I got to weave into it. It's not that cliched, thinly disguised romance or bromance, or whatever. It's different, it's a different set of circumstances than you're used to seeing."
The former Walking Dead frontrunner was hired to work on the script of director Gareth Edward's movie earlier in January.
Godzilla will arrive in cinemas on May 16, 2014.
