I read the books the day before I had met with the director Catherine Hardwicke. The first I heard of it was my agent called and said, 'Do you want to be in a vampire movie?' and I said 'No.' I thought it was like a zombie, blood-and-guts, vampire movie.

What I like about the third movie is you get to see a side of Carlisle you haven't seen before. You actually get to see what his vampire capabilities are because there's some great battle sequences. It's my favorite book. Carlisle is holding on to that humanity. He doesn't want to be a vampire.

Twitter for me is a form of entertainment for the followers and it's also a source of information. I try to tweet things that I think might make people smile, or to share information that I want to get across, like an event like this that can inspire other people to get involved. I try to mix it up. I think that is a reflection of me - a family man, an actor, and a philanthropist.

There were days when I was literally running for hours in the forest and then I'd jump on a plane and then I'd be on the 'Nurse Jackie' set. I was going from Vancouver to New York every three days. For me, it was really invigorating.

When you are creating your character there are a lot of questions and sometimes you doubt if you are making the right choices.

Sometimes while you're cooking it's messy but the outcome is good. The end result is all that counts.

I don't know what the future holds. I just try to do roles that I haven't done before.
