We've been shooting the last two weeks with a lot of vampires. I don't want to give away too much, but if you've read the books, it's the standoff with lots of vampires in play. There's like 70 people going through the works at once. It's a little maddening, but fun. We shot pretty much the ending of the two movies the other day.

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.

You'd come in in the morning and put your contact lenses in and they'd put your makeup on. I tried to stay out of the sun, because the more color you had, the more makeup you had to wear, to cover your color.

We've always had to worry about the electrical grid and nuclear facilities, and they remain a concern; but cyber-terrorism, you know, which is a word that you hear more and more, I think is a reality.

My advice has always been to study the craft of acting if you want to be an actor. There are many great schools that teach acting. NYU being one of them.

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.

I like playing the contrasting roles. It what inspires me to act. If I look back on my career I am happy that I have gotten to play a wide variety of different roles, from Mike Dexter, to Van Ray in Fast Lane, to Dr. Cullen to Coop.
