What do you know about the footage?
I know two people who have seen what he had back when, and I know their views about it. I don't believe it would be proper to say any more than that. I've seen a little of it, but nothing worth mention.
Besides, we don't really know what's in this movie. Kelly may have added new footage, or changed things in other ways. We'll just have to see what he's got when we are able to.
