Ebirah, Horror of the Deep, is… on the one hand, it’s a lot less weird than recent Godzilla movies I’ve watched, in that it’s not batshit crazy. But on the other hand, it’s actually weirder in some ways, because it’s heavily James Bond influenced I think? And also, this was probably the moment where Godzilla made the transition from anti-hero to good guy, which… I certainly see how it has affected all the future stories, making this clear delineation that he will never again be an existential threat. But I’m still not convinced in the contexts of these movies that it was a good idea, is all.
So get this. This dude’s brother is lost at sea, so he tries to enter a dance-a-thon to win a yacht, but since it’s already three days in, they won’t let him join. So instead, he and two other failed contestants and a third guy all steal a yacht together, semi-accidentally. Then they see a giant crab thing and shipwreck on an island, which is inhabited by a supervillain lair, except without a specific obvious supervillain. Instead, there’s a scientist (I think?) working on nukes, and an eyepatch guy who leads a group of henchmen with machine guns from place to place all over the island, just randomly firing at our heroes but always missing them. It is also inhabited by slaves from Infant Island (famously the home of Mothra) and by a comatose Godzilla, the latter of which is too coincidental for words, and yet here we are.
So anyway, these guys try to figure out how to escape, and how to free the Infants, and how to deal with the giant crab monster (who I believe is referred to exactly once by name?), and eventually there’s a lot of kaiju-fighting, to dance-a-thon music. Oh, and in case you were wondering, Mothra 2 finally grew up and is no longer a caterpillar.
