Can I sue the makers of IRON MAN because there was no actual iron in the suit?.....or even an actual man in the suit?....
There was - a man, in the suit, I mean. At least in some of the scenes. There actually was a practical suit, even if it was made out of plastic and resin instead of iron and he didn't always wear the whole thing and it was CG in some of the scenes.
And even there, the Mark 1 practical suit weighed 90-100lbs, according to Favreau and the stunt guy who wore the thing. That's actual steel there - which is largely iron. There you go, a real iron man.
Find a new target, there're plenty out there.
