Left Behind: The Movie is a 2000 feature film based on the first of a series of novels of the same name by Tim LaHaye and Jerry B. Jenkins. Badly acted, badly plotted and with just enough visual elements to give it some substance, Left Behind will appeal to Christian Bible literalists who see the Apocalypse just around the corner and fervently hope that they will be among the chosen few who will not be left behind during the Rapture.
It's after the mysterious disappearance of people all over the world, including many on an airline flight and lots of children -- far more than the 4400 that have also been the subject of a TV series and novels -- that the movie turns preachy. By the end of the film one of the characters has a complete conversion experience having witnessed first-hand the work of the Anti-Christ in the form of the Secretary General of the United Nations. The idea that the United Nations and two individuals, who are murdered by the Secretary General in front of UN delegates and security officials, can somehow plot to take over the world and dictate seven years of peace through the food supply is one of the most unrealistic and far-fetched conspiracy theories I've ever encountered.
For those who can't get enough of the Christian Apocalypse, two other movies based on the novels, Left Behind: Tribulation Force and Left Behind: World at War, are also available singly or as a collection with the first movie.
