IN THE MOUTH OF MADNESS is one of my all time favorite horror films. I do not want to give any possible spoilers at all - can I really spoil a film released in 1994? - so I will keep the details to a minimum. The best way to describe this film might be as a homage to H.P. Lovecraft directed by John Carpenter. That should be enough! IN THE MOUTH OF MADNESS is an underappreciated effort starring an underappreciated Sam Neill. This film will leave you wondering at the end. Give it a chance and I do not think you will be disappointed.
