Giants have intrigued humankind since time immemorial.  The creation myths of the world often feature giants.  The Old Testament describes Nephilim giants who were the fathers of the gods of old. The ancient Indian Hindu texts describe Diatya, a race of giants clashing in the sky.  In one Chinese creation myth the earth is formed by a giant horned creature, grown from an egg, whose body is the earth.  The knights of Europe fought dragons.  Perhaps it was the remnants of the dinosaur age, the wooly mammoth or a few large birds that swept the sky and permanently etched giants into the human mind.  Many great religious literary works of the past have sought the giants and movies have reached for the same heights.  The giants are brought to life in film, existing there, immortal as they are.
