My worst habit is whistling while I sleep.

I'd be lying if I said it wasn't fun to go to these nights out, like the opening of a film or something, but I dip in and out of it.

I wasn't into Tolkien at school really. But the story is timeless, the themes that it touches on are contained in cultures all around the world. The innocent on a quest, the pretender, an inanimate object that holds evil - it's really strange that these themes are there in so many different countries' folklore.

Hobbits are a lot like Scots. It’s all about nature and enjoying their land, which is a very Scottish thing.

But you talk to most filmmakers and it is six, seven, eight years trying to get things off the ground. It is incredible really.

I was probably about fourteen I think, and probably like every boy who's fourteen that writes a song, it was about a girl. It was about a girl who I really liked, but she didn't like me as much as I liked her. I think most guys go through that.
