- also, remember the '70s was a time of economic crisis and contraction of the Japanese film industry. So effects in things like the Godzilla films of the time are interesting once you get into how these films are made because you see them try to figure out how to make interesting looking stuff while using vastly less resources then before. One if the solutions was to go all in on pyrotechnics! The chemicals were cheap and effects director Teroyushi Nakano fiddled with the formulas to get just the right smoke for the visual. That's why Godzilla vs. Mechagodzilla is a movie that's 50% stuff blowing up!
