One scene in the original Ice Age movie takes Sid through a strange ice cave, where it appears to predict the defining images of the next four movies in the series. The Ice Age franchise is a popular animated series, with all five movies in the main Ice Age timeline and its spinoff raising $3.2 billion at the box office. The original installment, arguably the best Ice Age movie, is a relatively simple story about a mismatched group of lovable prehistoric creatures trying to return a human baby to his family before the sequels expand the world.
