The Gospel According to Stephenson is a vampire movie with a secular message. I learned about it from The Friendly Atheist.
The basic story concerns the appearance of what appears to be a supernatural being in our modern society — Stephenson — and how the worldview of the people he comes in contact with colors their perception of him.
Those with a supernatural worldview — “The Believers” — see him as an evil being needing to be stopped in the name of God and morality. Those with a naturalistic world view — “The Skeptics” — see vampirism as a disease that needs to be understood, and if necessary, cured. The Believers call in armies of Christians armed with crosses, wooden stakes and holy water. The Skeptics call in reason and science in the form of the CDC.
Stephenson is possibly the first movie to deal with the vampire myth from a skeptical POV. It is going to be partially crowd funded, so you should chip in! Help make this happen!
