Re: Iron Man 3 confirmed
Fing Fang Foom was never mystical, as I recall. There's nothing magic about him. He's an alien who happens to resemble a chinese dragon(maybe the source of legends about dragons in china, for all I know). And the components of his downed ship's hyperdrive is what the Mandarin uses to make his rings.
My God, did that smell good!
With proper execution, ANY movie idea can work.
