In 'Tintin,' it's like a live-action role. You're living and breathing and making decisions for that character from page 1 to page 120, the whole emotional arc. In an animated movie, it's a committee decision. There are 50 people creating that character. You're responsible for a small part.

I'm definitely moving more towards directing now.

Gollum is Gollum - though in 'Lord of the Rings' he's 600 years old and in 'The Hobbit' he's 540, so he looks a little bit more handsome.

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.

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.

Where as you go into playing something like Ulysses [on Black Panther], you go - I'm going to have this haircut and this cloth, you draw from different stimulus.

Performance capture is a technology, not a genre; it's just another way of recording an actor's performance.
