Movies like mouth of madness

In the Mouth of Madness is a 1994 American horror film directed and scored by John Carpenter and written by Michael De Luca. It stars Sam Neill, Julie Carmen, Jürgen Prochnow, David Warner and Charlton Heston. Informally, the film is the third installment in Carpenter's Apocalypse Trilogy, preceded by The Thing and Prince of Darkness.

In the midst of an unspecified disaster, Dr. Wrenn (David Warner) visits John Trent (Sam Neill), a patient in a psychiatric hospital, and Trent recounts his story:

Trent, a freelance insurance investigator, has lunch with a colleague, the owner of an insurance company, who asks Trent to work on his largest insured: investigating a claim by New York-based Arcane Publishing. During their conversation, Trent is attacked by a man wielding an axe who, after asking him if he reads Sutter Cane, is shot dead by a police officer before he can harm Trent. The man was Cane's agent, who went insane and killed his family after reading one of Cane's books.
