Isn't it iron-ic?

Robert Downey, Jr.'s turn as Tony Stark, a.k.a. Iron Man, in the Marvel Cinematic Universe is without question the single biggest success marker of his lengthy career, but once upon a time, he wasn't such a fan of Ol' Shell-Head. In fact, when he was 16, he was suspended from high school for a day after he nabbed a classmate's copy of an Iron Man comic book (The Invincible Iron Man, to be exact) and called the kid a "nerd."

Even though Downey obviously lacked an early appreciation for the character, he eventually did come around, for obvious reasons, and says he takes his stories "as seriously as Shakespeare."
