What's interesting to 'Vikings' the series is that Horik is so blind in his greed and his desire for revenge that he can't hear reason, and he's probably so insecure about Ragnar that he won't take his advice. And straight up, honestly, if you ever have to say to someone, 'Hey, remember, I'm the king?' It's too late, and you've lost your authority.

If someone said, 'Think of a happy place for you,' I'd say a glacial plane near the South Pole, the wind howling, nobody in sight, a shack with a pot-belly stove and some tea.

I play grizzlys, but I'm not a grizzly. I'm a song-and-dance man.

It's always surprised me that the most successful and really amazing shows are also the happiest environments and very welcoming.

Even now, when people come up to me and say, 'My kid's an actor. They want to move to L.A. What should they do?' Even if you wanted to help them as much as possible, there's really nothing you can do.

One of my best and dearest friends in the world is this guy named Robert Burke, who was in 'Rescue Me.'

I'm into cars and motorcycles, but I'm not crazy. I still have a couple motorcycles, but as you get older and you have kids, you develop a little bit of caution on the road.

I feel like I'm really lucky because I get to sometimes maybe vibrate at a frequency that's a little deeper and darker than people anticipate.

The desert feels Irish in a way - lonely and barren.

To me, the people on 'Copper' were rock stars. Before I joined that show, I loved that show.
