Dark Dungeons is a notorious 1984 Jack Chick tract that warns the readers about the danger of being embroiled in soul-destroying Satanic cults through playing Dungeons and Dragons and other RPGs. A group of fan-supported media creators obtained a free film license from Chick to make a film based on the comic, and they’ve released a trailer that hints at a very funny future for the project.
