“And to tell you the truth, I’ve no interest in doing Fantastic Four, frankly, and there have been no discussions about it. I think more than anything after Potter, I need a bit of a break. And there are two or three things I really like a lot that would come before anything else. Even though they’re not announced, there are a few things that I really, really like a lot that I’m keeping under my hat to make sure they’re cooking. So my schedule wouldn’t allow it anyway, but, again, I haven’t had any discussions with anyone.”
