With all this Rapture talk lately, I was reminded about a movie I watched a couple weeks ago (the first part of a trilogy), and saw the last two tonight:

Left Behind (2001)
Left Behind II: Tribulation Force (2002)
Left Behind: World at War (2005)

These are Christian-centric movies, but yet, they're made as mainstream features. If you want to get what the Rapture is (can be) all about in modern times, then take a look. I'm Christian (Catholic), so didn't take any offense at the scripture embedded within. These aren't the best movies ever made (nor the worst), but the subject matter is interesting, timely, and a bit inspirational. Sadly, Part III ended on a cliff-hanger, and IV has yet to be made as far as I know....
