In the Mouth of Madness (1995)

All things considered, Carpenter's absolute peak. He's always shuffled between 3 modes, often within the same movie: campy, spooky, and horrific. But this is the first time he didn't shatter the test tubes. Don't expect a true-to-the-source Lovecraft movie; this one's pure Carpenter. Watch it with the volume LOUD. "I think, therefore you are."
