What is your character's defining moment?

I'm hoping it will be the killing of the Witch-King, but I haven't seen the movie so I can't be sure. Either that, or probably the scene with Aragorn in the second movie with the sword.

Describe Peter Jackson in three words.

Oh God, oh god…Shy. Passionate. I could say genius, really, but I don't know whether to try…unstoppable. Hold on, force of nature -- that's it. Force of nature.

Why do you think Rings has been so successful?

For so many reasons. Because it's such a great book and then because you've got Peter and his whole team bringing it to the screen, with the sort of integrity and passion that they brought to their work. I think that's why it's been such a success - and that people love the story to start with.

What is your favourite piece of Lord of the Rings memorabilia?

My sword. They gave me a belt as well, but probably my sword - the sword was the best thing to have.

Which of the other roles would you like to have played?

God, I change this all the time. Not that I could have played him, but it would be fun to be Gandalf.

What was the toughest thing you had to do?

Picking up the script changes, actually. Also, leaving when we finished the original shoot.

How does it feel to say goodbye?

You know, it was sadder than I thought it would be. I mean, if you want to see people you will always see people again, so that doesn't have to be the end of that at all. I think there's a good sense of achievement. We've been with it for three year now - longer for some people - and there's a great sense of achievement in actually having finished it, the fact that it's actually going out with 100 per cent energy still attached to it instead of it dragging on for a long time.
