I think there is something about a good person doing bad things for what they consider to be a good reason. Then the battle is on to almost prove to the audience that it's justified. How far can you go with that? How far can that character go before people won't accept it? Trying to walk to edge of that line is a challenge.
No money has ever been spent on 'Peaky Blinders' in terms of publicity, there's no massive campaign - because it's the BBC you just get the trailers. But what's happened is people have found it for themselves and I think the loyalty is greater when people find than when they're told to watch something.
Getting 'Millionaire' right was as hard as writing 'Dirty Pretty Things.' Harder. In the pilots, contestants kept wanting to take the money; we had to find ways - the lifelines - of keeping them in the seat, answering the questions. But there is so much snobbery about popular culture. A game show just isn't valued as much as a novel.
True stories are always good because they're so odd, and so unlikely. It's always good to have a world that people don't know about - a world that hasn't yet been done. It's like treading on fresh snow. You're the first one there. It always feels good to be dealing with a period of history or a world that no one else has dealt with.
