Jack Chick's notorious comic tract Dark Dungeons taught us all that playing Dungeons & Dragons will ruin your life and condemn your soul to hell. Now that comic is a movie all about the satanic pleasures of RPGs.
You can watch the full 39-minute for $5 at the Dark Dungeons movie website. Judging from this preview, it looks like its tongue is planted firmly in its cheek even as its actors play their roles with straight faces. I imagine it can be enjoyed by those of us who take ironic delight in Chick Tracts as well as those who believe D&D is a gateway to occult powers.
