What if Stephen King was writing horror novels under the influence of the eldritch horrors of H.P. In the Mouth of Madness opened in theaters in February of 1995, decades before horror was really taken seriously by mainstream critics. Of course, the score alone also makes any John Carpenter movie worth it. In the Mouth of Madness first appeared on Blu-ray in 2013, followed by DVD and Blu-ray re-releases later in the 2010s. Arrow Video’s new 4K UHD disc marks the first time the movie has been available to buy in 4K, however.
