Arrow in the Head has revealed the trailer and artwork for Beyond the Horizon of Madness: The Horrors of Sam Neill, a new documentary from Mike Gencarelli centered on John Carpenter’s In the Mouth of Madness and Paul W.S. Anderson’s Event Horizon.

Neill, who died July 13 at the age of 78, left behind an incredible genre legacy that stretched from playing the adult Damien Thorn in Omen III: The Final Conflict and starring opposite Isabelle Adjani in Possession to Dead Calm, In the Mouth of Madness and the sci-fi horror cult classic Event Horizon. And, of course, there’s a little movie called Jurassic Park, which remains one of the most breathlessly exhilarating theatrical experiences of my lifetime.
