The only thing about 3-D is the dullness of the image.

I find that in the process of making a film you're constantly discovering things that you never even imagined would work at the beginning.

Elijah can register such subtle emotion on his face that I loved doing close-ups on him. He really brings a superb emotional level to Frodo's scenes and although he is a very instinctive actor, we discussed the character thoroughly.

And so I look back on not just the last ten years but everything that I've done as being sort of an ongoing growing continual film school. I mean I don't think I've got to a point where I've achieved anything that feels like, a particular milestone, but there's still a lot more to learn and hopefully a lot more films to make.

Every film is a challenge. I always say that making a movie is like film school - you're always learning. But unlike most schools, you never get done with it. You never learn everything.

I think that George Lucas' 'Star Wars' films are fantastic. What he's done, which I admire, is he has taken all the money and profit from those films and poured it into developing digital sound and surround sound, which we are using today.

Actors will never be replaced. The thought that somehow a computer version of a character is going to be something people prefer to look at is a ludicrous idea.
