I think once those friendships, if you use that as an analogy, the friendships between the audience and the character is established, then you can start to take liberties. I believe that as this unfolds people will find the time invested worthwhile.

You work, especially in the movie business more than in TV, but you have an environment where people feel obliged to have an input because that's what they do, and I think sometimes it can clutter things up and make things more problematic.

There's lots of different ways of writing stuff and lots of different mindsets to have, but I think when it's your own creation, it's more pleasurable because you have total control.

There's more to come. Series 4 [of Peaky Blinders] is coming soon. But I'm proud of making my hometown, which is considered to be completely unfashionable, slightly fashionable. People actually know where it is now.

A creative person can suddenly realize it's not 90 minutes. They haven't got to do three acts, they haven't got to do the arc, but they can do other things. I think just as novellas turned into novels, I think that television series can begin to have that depth.

The sandstorm, which I think is an absolute triumph, could have been awkward. It's sex in a car, so who knows. And I think the rooftops look fantastic [in Allied].

It has to be an actress like Marion Cotillard [in Allied] because there are so many levels to it. It's set in the Second World War, when lots of people were doing things that, outside of a war, you wouldn't do, like killing and dropping bombs. She's doing things that one wouldn't approve of, but it's war.
