There's also sort of a mad men's, you know, a crazy person's determination just to keep going. And not give up. And a kind of rage. There's a deep rage in Voldemort against the world. Funny enough, when I saw my nephew Hera, who played the young Tom Riddle, Voldemort. He has such a wonderful quality of a boy's loneliness because the world has rejected him. Which is the beginning of a sort of rage against the world. I often remember that scene that Hera played, because it was such a good reference for that little lonely, isolated boy, who's decided he will not be defeated.
I don't think anybody who is evil, doesn't probably think their evil. They think they have a way of seeing the world. Which is their way. It's the right way. It's the way the world will work better if it's done like this. My way.
It's a very real threat, I think. That he will destroy all Harry's friends if they try to protect him. So I think Harry is heroic. I think he makes a very real threat. You must come. He can't get Harry. Because he's protected. He's surrounded by allies. It's his way of getting the person he wants.
Ralph Fiennes also talks about how physical his scene was when he confronted Daniel Radcliffe as Harry. And how they really fought.
