A few years ago, Blumhouse’s Ryan Turek and I were teaching a class on horror filmmaking at a convention in Los Angeles. There we met Joseph and Will Martinez, twin horror fans who were just starting in filmmaking. This morning they sent me their completed project, and it is fantastic! The short film tells the story of a young girl who dares to try out a local legend, knocking on the abandoned mine 3 times, supposedly summoning an evil witch. Please check out KNOCK below.
