Let's be fair. The reason this probably came up is someone asked McConaughey if he would be interested in a comic book role and he said he'd be interested if it was the right fit. That led to speculation of who he would play. I don't think this is anything beyond an unsubstantiated rumor at this point. That being said, I'd have far less problem with just Norman Osborn, as long as it isn't the Green Goblin.
