I'd already started directing short films when we were doing 'Lord of the Rings,' then videogame projects.

I love playing real characters... if they're not around anymore it's helpful because you won't get sued! But there's so much research involved and I love that part of the process.

My agent told me they were casting for the voice of Gollum. I hadnt read The Lord of the Rings, but I read the script and realized what an amazing role it was. I developed a voice for the audition tape, then met Peter Jackson and Fran Walsh at the auditions and fell in love with them both.

What's wonderful about Tolkien and Shakespeare is that they show up your own individual microscope. They're so infinitely vast. You can reinterpret them in so many ways. Each age will have its own resonance with Lord of the Rings.

I've done a fair amount of that stuff... when we did 'Lord of the Rings' the transformation sequence from Smeagol to Gollum was a 19-hour make-up job. You have to have a kind of zen button that you press and allow the mind to be focused in a certain way.

When you have children, you realize that at the end it's all about passing on, about handing down. The process of letting go, not attachment, but appreciating the beauty and value in the change, the transformation.

I stayed in Baghdad every summer until I was 14. My dad's sister is still there, but many of my relatives have managed to get out. People forget that there are still people there who are not radicalized in any particular direction, trying to live normal lives in a very difficult situation.
