Hang on... You think that Robert Downey Jr is snobby because of the amount of camera time on his face?
 * Downey has stated that he hated filming the Heads-Up Display shots, where he's in the suit, all claustrophobic with the close-ups.
 * If you hired Downey, you would give him that screen time, because of his charisma, and maybe because he actually is a great actor. And you want the character to have some emotion.
 * Which leads to the big one: Those fight scenes that Iron Man is in, with the helmet down. He's not acting. That's CGI metal where his face is (and entire body for that matter) - meaning that minus any voice acting and HUD shots, and because the character moves very robotically, there is virtually no acting, and no emotion in the character. Now, I'm not saying that voice acting can't convey emotion, but normally, voice acting is accompanied by an animated face. This is a still piece of metal. Voldemort's nose is a different story, because his face is actually there.
