I was a weed. Such a skinny little weed. I just couldn't put on weight; I couldn't put on muscle. I was the oddest shape. And I thought that was it: that's how I'd look for the rest of my life. And I'd beat myself up about it so much. But you change an awful lot. You're 16. Your body's not even halfway to what it'll end up being.
For your own self-respect and sanity, your creative freedom, you have to be careful that you don't rely too much on other people's opinions of what you do because it can stunt and inhibit you.
The gym is somewhere you can go to just forget for an hour what you do for a living, what you are doing on a daily basis. You just turn up and get on with it.
I come from a country that lives and breathes rugby, and I didn't think there would be anywhere else in the world that could be the same. But New Zealand takes it to another dimension. It's extraordinary how much passion Kiwis have for the game.
It was very weird because for a long time no one really recognised me from my films, but 'The Hobbit' has totally changed that, and I've had some really special moments, especially with youngsters.
A guy's biggest style mistake is definitely trying to look too cool. As long as you've got a good pair of jeans, a good pair of boots and a few good shirts, you're fine.
I was often looked at as a leper by kids at school because I was a Jehovah's Witness. They didn't like it - you were 'weird'. And on Saturday mornings, you'd be knocking at their doors. I remember standing there with my mum and dad, thinking, 'Oh my God, I know whose door this is, and I'll have to see them on Monday.' It was terrible.
I've had some pretty awful jobs that I don't miss, like working on a nightclub door, or compiling VIP lists at 3 A.M. in the morning, but sometimes it's just got to be done.
In 10 years, I'd love to live near the sea, in a warmer climate. I could see myself with three dogs... and it'd be great to share them with someone else.
As much as my parents were worried about me moving to London at 17, they could see that I was hungry to find my path. And it probably helped that they saw me succeeding at it, slowly but surely.
One thing Tolkien does incredibly well - and this is from a lay person's point of view; I am not scholar or anything - is that you don't have to make an effort to envisage the worlds that he writes about.
The truth of the matter is roles like James Bond are the ones that I look up to as probably the best roles ever to play. So that's probably my ultimate goal one day: to play James Bond.
Vampires were always able to transform into creatures of the night. The dark creatures like bats have always been associated with vampires and using the darkness to their own advantage.
I really loved 'Fast Five.' I thought it was a brilliant movie. I thought it was so well done, well directed. The action sequences were really well thought out. It looked fantastic.
When I didn't get a job, I thought, 'Don't worry, there'll be another one.' I still live by that now. Nothing really fazes me any more.
I've got two cows licks; when I was a kid, all the boys in school used to have curtains, and my hair never used to do that, ever! I always used to try, and I always looked like the geek.
'The Desolation of Smaug' stands alone as an action/adventure epic movie. It's visually stunning, and the 3D is incredible. Plus, it's directed by Peter Jackson, and he's extraordinary.
I used to take my car and go down to the South Island for five or six days and climb glaciers and jump out of planes and jump off bridges and go white water rafting - a bit of thrill-seeking.
I think the best directors provide you with a safe environment where they can instill you with confidence and allow you to try things out and not feel like you're failing or that you're doing it wrong.
There are certain tuxes you can get away with a black tie, but with others, you'd be dishonoring the workmanship if you didn't wear a full bow tie.
