I'm currently reading Lovecraft's work in chronological order, and I'm accompanying them with as many adaptations and films with Lovecraftian themes as possible. I've compiled a list of the stories and their corresponding cinematic adaptations. Would anyone care to add to the list if you can think of any I missed?
Which ones are your favorites? Which ones do you hate?
