In a recent Horror Homeroom Conversations podcast, we were discussing two ecohorror films – The Great Alligator (Sergio Martino, 1979) and Alligator (Lewis Teague, 1980) – and came to two conclusions. First, that Jaws (Steven Spielberg, 1975) casts an enormous shadow over the natural horror films that followed. And, second, that there is a formulaic plot structuring such films, one so incredibly common as to seem fixed, inevitable. As we described this plot in the podcast: 1) humans tamper with the natural environment; 2) as a result, a creature launches a rampaging attack on said humans; and 3) the besieged humans fight back – almost always winning. Given our discussion in this podcast, and my recent immersion in natural horror films, I was very excited when Xavier Gens’ new genre film, Under Paris (Sous la Seine) arrived on Netflix. And I was right to be excited: Under Paris is a great natural horror film and now resides among my top 5 shark horror films (I’ll give the whole top 5 at the end!)
