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.

The Vikings certainly didn't write anything about themselves; it was not a literate, but rather a pagan, culture. So what we get was written later by Christian monks. But there were occasional reportings and recordings of people who had traded usually with the Vikings.

You have to create characters - certainly in series TV - who people engage with. They don't have to be nice; you don't have to agree with them. But they do have to be compulsively watchable and believable and human, and you want to know what happens to them.

Of course I had written a film about Elizabeth I, and I loved the Tudor period, and I think at the time Working Title and I had debated on whether to do Elizabeth I or Henry VIII. I'd always wanted to do Henry VIII. Like Elizabeth, I'd had this feeling that it had never properly been addressed.

Nobody knows what really happened in any historical period. There are some periods where we know more than others, though.

I felt that a lot of Viking culture had been caricatured and misconstrued. After all, they were far more democratic than the Saxons and the Francs, who were exercising really hierarchical social structures at that time. The Vikings had popular meetings where everything could be discussed.

It works better if your lead character is complex and interesting and not perfect.

I'm very bad at delegating writing responsibilities, because I've never been able to do it; I've never had any help or looked for any help.
