The original Godzilla (1954), especially the original Japanese release, is more than a mutant monster movie of the atomic-scare fifties. It is a stark disaster thriller that evokes the terrors of the bombings of Hiroshima and Nagasaki and the lingering poison of the nuclear radiation. The two destructive forces come together in a screaming atomic lizard, a dinosaur roused from dormancy by the lingering radiation and set loose for a new nuclear holocaust, and the black and white photography lends an atmosphere of dark and doom.
The sequels are a different story. The films went color. The special effects of cities stomped to rubble by a radioactive dinosaur became a kind of giddy entertainment instead of a nightmarish metaphor. And as far as the movies were concerned, Godzilla was no longer a post-nuclear plague unleashed upon Japan let alone a villain. He was a character in its own right and the stories that followed his 1954 debut mutated (so to speak) into monster smackdowns that allowed audiences to root for his victory against a new menace to civilization without any sense of irony. While not exactly a friend of mankind, he turned into a protector of Earth when it is threatened by other monsters and, later, alien invaders. This was Godzilla’s turf and no one was muscling in.
Destroy All Monsters (1968), the ninth Godzilla film and the twentieth kaiju (giant monster) movie from Toho, returned Godzilla godfather Ishiro Honda to the helm.
