You've got to do the Mandarin. The problem with the Mandarin is that the way it's depicted in the comic books, you don't want to see that.
He has 10 magical rings — that just doesn't feel right for our [franchise]. So it's either tech-based, or the rings are not really rings. But maybe with Thor and all those others, you'll introduce magic to that world and it won't seem so out of place.
