1 of the best Godzilla movies with a political message warning about pollution
The original Godzilla movie was a warning about the effects of nuclear weapons. Godzilla vs Hedorah had a similar message about the threat of pollution. In America the movie was released as Godzilla vs the Smog Monster because Hedorah was the result of all the waste dumped into the ocean. That’s emphasized  right at the start as the credits show all kinds of garbage and sludge floating on water. This makes the film openly political.<br /><br />One good thing about the movie is that it gets right down to business. A marine biologist shows how damaged a bay is by pollution and the monster appears immediately followed by Godzilla. By this time the big guy was a hero so he’s portrayed as an environmental warriors attempting to save the planet from Hedorah and waste. There’s plenty of fight scenes between the two throughout the movie.<br /><br />Hedorah really stands out because it came in many forms. At one time it looks like a tadpole and then the next like a flying saucer. He also emits a deadly mist of sulfuric acid that destroys everything it touches. People are forced to wear masks to try to protect themselves which is of course symbolic of the deteriorating air conditions due to pollution.<br /><br />The film also includes a lot of 1970s Japanese youth culture with some loud Acid Rock scenes. One occurs during a youth protest against pollution on Mount Fuji again emphasizing the political nature of the film.<br /><br />This really is one of the best Godzilla movies because of the action along with the message.<br />C

Here is a brief synopsis of the title : We humans are destroying our environment - and now there is a price to pay. From the sewage and sludge pumped into the sea, life degenerates, then mutates, creating a mega-monster, Hedorah . A radically ugly creature, this mammoth of muck swims, walks and flies, pausing only to inhale noxious smokestack fumes. He emits poisonous gasm crushes armies and annihilates cities while thriving on the toxins of our ecosystem. Cannons and missiles can't harm him, but his nefarious stench summons the attention of Godzilla(r), whose own refuge is threatened. Now, the monster of waste...is about to get wasted..
