Disaster films are sometimes a subgenre of action films, but not always. They can include natural disasters, man-made disasters, pandemics, etc. I won't be including anything sci-fi, like alien invasions, nor anything supernatural, like zombie apocalypses, nor anything post-apocalyptic, or really... there's probably any number of disasters I won't include here. But we'll see how it goes. Um... I'm pretty sure I saw Outbreak in 1995, but that was well before I started reviewing films (before I even had a website), and I don't expect to ever watch it again. In fact I don't know if I'll be reviewing any epidemic/pandemic movies, because I'm just not that into them (especially after living through a real pandemic in the 2020s), but I at least wanted to mention that they're a part of this category.
