On Friday, it was revealed by ABC News that one of the famous shots of supposed Antarctic ice shelves in the film was actually a computer-generated image from the 2004 science fiction blockbuster "The Day After Tomorrow." [audio available here]
Adding delicious insult to injury, this was presented by one of ABC's foremost global warming alarmists Sam Champion during Friday's "20/20":
