While i do not subscribe to the Rapture theory (seeing it as the resurrection at the end of the Great Trib.), it did spawn a lot of movies. The best i though was "Days of the Beast," hard to find, and it has much that corresponds to how things are moving today. Substitute the rapture for the res. at the end of the trib.
Maybe you were thinking of Megiddo omega code
