Antrum: The Deadliest Film Ever Made takes it a step further. The first 10 minutes and closing credits of Antrum are short documentaries about the history of a lost horror film called Antrum. Film historians and critics describe the legacy of a tiny, independent, barely-released horror film. Apparently, anyone who sees the film will die shortly after watching it. Entire festival screenings burned to the ground, and festival organizers planning on rejecting the film died before the rejection could be made official.
