Jon Favreau later called in to explain the significance of Howard's Iron Man head: "There's not a real Iron Man. They make a lot of helmets when they first produce the movie...I will never let you have something in your house that Ralph has."
Jon said it truly was one of a kind--or three: "There are only two people that have what you have that I know of. Robert Downey Jr. got one for his birthday and I have one."
Howard was indifferent: "I'm happy with my Iron Man head, ok? It's just that when I throw it out the window, I won't be so sad."
