Has anyone ever seen this psychological horror movie made by John Carpenter in 1994? The plot concerns private investigator John Trent (played by Sam Neill) who is asked to search for missing writer Sutter Cain, the author of a number of highly popular horror books, by Cain's publishers. Trent then goes on an increasingly surreal and nightmarish journey to find Cain who is in the process of writing his latest work "In the Mouth of Madness", and it is implied that Cain has the ability to alter reality via his fiction. To those who've seen the film, what are your opinions of it?
