Fan Casting Actors who could be or could have been Mephisto

I made this partly because of the news about Sacha Baron Cohen playing Mephisto, even though I only consider it a rumor for the meantime. This story might as well have been "Actors who could be or could have been Satan/The Devil" or "Actors who could be or could have been Mephistopheles" since Mephistopheles is a figure in the public domain who Marvel made their version of the Devil in their universe, but since there are multiple stories about Iron Man, Captain America, Spider-Man, etc., what's wrong with this?
