Yeah, that's a good one, Don. (Story's called "The 9 billion names of God", coincidentally. :-)

IIRC, "Nightfall" is also interesting because it shows religious belief ("our god says it won't happen") against the scientists' discovery that it's going to happen. And the scientists end up as the scapegoats when it *does* happen.

Also don't forget "Pitch Black" which was a cracking little film.
