The Fly
In 1986, David Cronenberg directed this nasty looking monster movie, perfect for Halloween. Jeff Goldblum plays a scientist who goes too far with an experiment and somehow turns himself into a buzzing and annoying fly. It's both tragic and deeply fascinating
Salò
In one of the darker films on this list, Salò follows a group that captures and tortures teenage men and women. They are subjected to humiliations of sexual acts, extreme bouts of pain, and terrifying moments. These men want only the worst for these teens, and it's scary to watch.
