Did You Know?

This was the first film that featured Kenpachiro Satsuma to wear the Smog Monster suit. Though small in stature, Satsuma was quite strong for his size, and was the only one capable of supporting the 300 pound suit for long periods of time. (Though there were some wire works to help support.) Satsuma then went on to wear the Gigan costume for the next two films. After a break of over 10 years, he would be asked to wear the Godzilla costume for Godzilla 1985, and would continue to wear it through the Heisei series, and retired after Godzilla vs. Destroyah in 1995.See more »
Revealing mistakes: When the child notices Godzilla from far away on the roller coaster ride, it is clear that "Godzilla" in this case is just a badly drawn blotch of paint, which also appears to be far too dark for its supposed environment.See more »
Dr. Yano:Do you know what a meteor is?
Ken Yano:Sure, it's a falling star that falls to earth.
Dr. Yano:Well, Hedorah (the Smog Monster) attached itself to one of those stars.

Campy Godzilla Fun, 22 August 2005

As the 1970s began, Godzilla started to turn into a much more campier, hipper if you will, Japanese institution. There is no evidence of that more striking than Godzilla Vs. the Smog Monster(Hedorah) with its cartoonish sedge-ways and psychedelic dance numbers, etc... I loved this film as a child. I remembered some scenes very well: a young boy on a rock calling, "Papa, Papa" and the scene with an oil/sludge covered cat amidst garbage and waste. The environmental issues were lost on my young brain, but having had a chance to see the film somewhat recently I have seen the obvious nature/message inherent in the film. And having seen the film again, I find that I like the film a lot less than I did as a child. Its magic didn't hold up for me, and I started to ask myself why? What could make the difference? Well, the story really is quite transparent as a young boy and his family(father a scientist)discover a new creature in the ocean that when dried turns to a cakey dust that when introduced to water again - creates new life. The scientist also learns that this new organism that feeds on waste has the ability to grow rapidly. Soon it grows to monster proportion as a giant black thing with glowing red eyes, destroying much of Tokyo and Japan, waiting to fight with Godzilla. While this film does indeed have some nicely shot, effective scenes, the story and the pacing just seem a bit strained. Hedorah is a pretty neat looking creature, and some of his fights with the big lizard are very rewarding. The film; however, doesn't have the sense of seriousness(if you can believe this?) that the earlier Godzilla films had. While ostensibly teaching about the evils of pollution and misusing the environment, Godzilla Vs, the Smog Monster is really nothing more than a very campy film of the big old green guy and a big pile of sludge.
