Honestly, saying "we're going back to the original 1954 Godzilla for inspiration" bores me at this point because it's so often said. It's been an oft-repeated mantra by anyone behind something Godzilla related probably ever since the Showa series ended and the many revival attempts began. Despite being the stated M.O. of most Godzilla films for the past 30 years it's pretty much always superficial, ending up as either lip service or at most just manifesting in a few scenes (like in Godzilla 2014).
But now I'm beginning to be pretty interested in the idea of Godzilla Resurgence going back to 1954 for inspiration, because it feels like this may be the first film to actually tackle that in earnest since The Return of Godzilla's straightforward, if nowhere near as impactful, attempt. I mean, we know hardly anything about the film aside from "Godzilla vs. Japan," but seeing that Godzilla's design reflects pre-production concepts and designs from '54 is fascinating. I've got this strage sensation of anticipating something that I was initially blasé about!
Are there any things from 1954 that you'd really like to see reprised? I'd like to see the practical effects of Godzilla's radiation addressed: making people sick, areas being quarantined. It's an interesting idea that's rarely used.
