When 'Line of Duty' started on BBC2, there was a feeling that it couldn't ever become a big show because the BBC2 drama budget is much smaller, and a returning cop series would take away from the Stephen Poliakoff/David Hare stuff that they love to commission.
The world is a horrible place, but no one worries because we have all been pacified by anodyne television in which incorruptible cops solve crimes, crusading lawyers keep the innocent out of prison, and streetwise social workers rescue children from abuse.
People are used to watching cop shows in which the cops are very straight down the line and they solve the crimes, but I think people actually have a much more sophisticated and varied view of the police.
I believe that attributing flaws to medical characters makes them not just doctors but something more. It makes them people.
It's always useful to know that people are emotionally invested in a series because it means that you can take them down a certain road, and they should be interested.
I love to do things that kind of mess with the movie formula that you can always find the right place to park; you've always got a phone signal. And I think audiences really respond to the limitations of real life when they intrude on drama.
I think once you do the unexpected, and you take the viewers to a position of discomfort about being able to rely on characters surviving, then it does completely affect the way in which the drama is viewed.
I think it's hugely important to have a strong episode one; you can lose an audience so quickly now. You can't afford to take the attitude that you will use the first one as an introduction and save the high drama for later.
I remember watching TV as a kid, and whenever there was some sort of jeopardy involving the hero, I could reassure myself that they were what I'd call a 'can't-die' character, so everything would be OK.
In the modern workplace, sexism has adopted a more subtle persona; therefore, people can be accused of sexism where it's far harder to determine whether they're actually committing sexism or thinking in a sexist way.
You can have characters that say one thing and do another, and in certain kinds of drama, you can't get away with that because the audience will become confused - or certainly, the commissioners will become confused and tell you to stop doing it!
The idea of a physical stigma is quite appealing. When I wrote the book of 'Bodies,' there was a lot of that in the book about how there are physical manifestations of psychological problems - I think it's described as 'Narrativizing The Body.'
I tell the truth where it's the ethical thing to do, but in terms of entertainment, there's a certain fun and enjoyment that can be added to the experience by a few judicious lies.
