The American obsession with 'Downton' amuses me slightly because it's such a fiction. I've always been questioned about my historical veracity, and 'Downton' just flies past, when it's completely made up.

I wasn't setting out to write a documentary; if I had, I would have done it in a completely different way. I was asked to write a drama that would appeal to a big audience in America that had no knowledge or interest in The Tudors at all.

The key for me with historical characters is they're interesting because they're human beings. A little bit of Hemingway goes a long way here, but journalists and writers should honestly look at their material and have a real interest, a real passion in what they want to write, and they should also have a lot of knowledge as well.

I've found that using historical material and being rooted in historical material is liberating because I always think to myself, 'Well, this actually happened, and this is fantastic!' That's why I don't like fantasy, in a way. Because it's sort of in emptiness.

When you're making a TV drama, the showrunner is God, and so however onerous and difficult and consuming that responsibility is, you're being treated with respect, so it changes your whole outlook to the production. You're being asked about costumes, set design, music, every aspect of the show.

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.

For 'Vikings,' we have to do so much outside shooting, and it's normally - I think with American shows, it'll be 60 or 70 percent inside and a little bit outside, but with us, it's almost 70 percent outside, and that's huge and really difficult.

People offer me loads of stuff, and some of it I like, but I just can't do it because I can't write it all. So I might get in the position where I have some sort of company and just write maybe the first episode, but these are love projects, in a way.

Once I engage in something, I really engage in it, and I love the process of reading and researching because I come from an academic background.

I couldn't give 'Vikings' away - I mean, I love these people. And I'm not sure anyone else writing it would necessarily have the same feeling towards the characters that I do.

When you're a screenwriter working on a film, you're not really even welcome on set, even if you know... When I wrote 'Elizabeth' and Shekhar Kapur was a friend of mine, but I wasn't really welcome on set, because the director is God and it's a very difficult position for a screenwriter who's put so much passion into that, into the writing.

People love cliches. If you can give people cliches, that's very good TV, then.
