I think the context of an hour-long drama gives breathing space that you don't get in a film.

Scotland is the only case in the world where the poor part of a territory wants to separate from the rich part. If independence came, one option is to keep the pound as its currency, so that all economic decisions will continue to be taken by the Bank of England.

I will say that anyone who supports Scottish independence should go to Athens. Because nothing works. It is a disaster. It is a ruined, dirty place where people do not have money or future prospects. The day one after independence, Scotland would be worse.

I really wanted to write the way Kubrick makes films - 'Strangelove,' '2001', 'Clockwork Orange', 'Barry Lyndon' - they're all so different.
