While I haven't read Tim LaHaye and Jerry B Jenkins' Left Behind series, I know many people have - and the trailer for the movie based on the novel, is now out.
Starring Nicolas Cage, Left Behind will be released in October.
An airborne Boeing 747 is headed to London when, without any warning, passengers mysteriously disappear from their seats. Terror and chaos slowly spread not only through the plane but also worldwide as unusual events continue to unfold. For those who have been left behind, the apocalypse has just begun (find it on Goodreads)
and for the movie:
A small group of survivors are left behind after millions of people suddenly vanish and the world is plunged into chaos and destruction. (on IMDb)
