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.
The film pays tribute to the work of seminal horror writer H. P. Lovecraft, with many references to his stories and themes. Its title is a play on Lovecraft’s novella, At the Mountains of Madness, and insanity plays as great a role in the film as it does in Lovecraft’s fiction. The opening scene depicts Trent’s confinement to an asylum, with the bulk of the story told in flashback, a common technique of Lovecraft. Reference is made to Lovecraftian settings and details (such as a character that shares the name of Lovecraft’s Pickman family). Sutter Cane’s novels have similar titles to H.P. Lovecraft stories : The Whisperer of the Dark (The Whisperer in Darkness), The Thing in the Basement (The Thing on the Doorstep), Haunter out of Time (The Haunter of the Dark/The Shadow Out of Time), and The Hobbs End Horror (The Dunwich Horror), the latter also referencing Hobbs End underground station from Nigel Kneale‘s Quatermass and the Pit.
The film can also be seen as a reference to Stephen King, who, like Lovecraft, writes horror fiction set in New England hamlets. (wiki)
