Godzilla
Godzilla is a film that, by modern standards, is rather lackluster in its visual effects and acting. Nonetheless, it displays exceptional screenplay and cinematography when compared to other films of its time, and explores many important themes which keep the audience thinking. It is an exceptionally old film which reflects the fears of the general population at the time. Specifically, Godzilla warns of the dangers of nuclear testing: a fear which was grounded in relatively sound reasoning. Mere months before the filming of Godzilla, the nuclear testing of America’s “Castle Bravo” irradiated the nearby Japanese boat Daigo Fukuryu Maru, a connection that can be drawn directly to the beginning of the film, wherein a fishing vessel is destroyed in the creature’s first display of power. This real life incident, like its counterpart in the movie, caused mass panic in Japan, as much of the crew became ill, with one even dying from radiation poisoning. Godzilla explores a narrative wherein nature strikes back at humanity for their irresponsible ways, and inspired a myriad of other films which explore the same topic. In the specific context of ecohorror, Godzilla explores themes of fear of the unknown, as well as the overwhelming power of nature and how it relates to mankind’s overall hubris. Additionally, this film is an exceptional (albeit dated) example of ocean ecohorror, which is why it specifically deserves a spotlight in this list.
