I got interested in the Vikings, and then you realize that there isn't much to be read about them because they did not write their history. It was written by hostile witnesses, by Christian monks and so on. From what I could see and understand, I was really excited about it. I loved their culture and loved their gods.

With 'The Tudors,' I had a huge amount of material, I mean so many books and so much stuff about what they really said. So, in a way it was kind of trying to strip it out and find the stories inside all this material.

TV drama - not always, but on the whole - were pretty appalling and very secondary, too. No one expected it to be like watching a movie; that was the point. But I think when you start watching 'Vikings,' it is like watching a movie - you're taken somewhere else.

Well, there's no question that the law passed in 1996 was flawed. It deregulated the wholesale market, meaning the price that the utilities had to pay energy companies for power, but not the retail market.
