Re: Ego: The Dark World
Why is it unlikely?
Ego is a major Thor villain; Ego is, literally, A Dark World; and we wouldn't have heard about casting because all of that would be handled by NASA. Or something.
I wouldn't see Ego in the literal comic book sense, of some planet with a genuine big-ass face on it shouting taunts at Thor; but I don't think audiences would have any trouble buying into the idea of an actual sentient planet. It's become a fairly commonplace theme in SF, most recently in Avatar. Just think of Pandora without the hippie feel-good vibe, and instead a murdering malevolence for a persona. Bam. There ya go.
