John Carpenter's Prince of Darkness!

[Marcus]

Great concept and I loved the movie but unfortunately there was a lack of funding to do what JC wanted to do. At least, that's the rumor.

The god Plutonium thing was a reference to nuclear weapons, I think, because it said it wouldn't save us. I assume it meant that our most powerful weapon would be no use against the anti-god. Again, it's just a guess but it makes sense to me.
