Iron has always fascinated humans for its strength and comparative indestructibility. Humans have always regarded iron as a symbol of strength. They have always looked at ways of amalgamating this metal into their lives in the form of armour or weapons, to offset their physical weakness. It complements human intelligence and spirit by adding to their defensive and offensive powers.
Iron Man is born out of one such fascinating plot by Marvel Comics, with a premise that appears impossible now but dreams of a path for future generations to explore. The movie Iron Man is an adaptation of this comic.
