I've been writing so much. And what happens with TV is that they split [Taboo] into two blocks, so you get a director that does four and another director that does another four. You commit yourself to seven days a week, for 12 or 13 hour days for a long time. I couldn't really do that.

A commission and an original are two different things, and both have their virtues and vices. A commission is a bit more collaborative, in that you outline the story that you think should be told, and then you write it.

Suddenly, after years of television being the poor relation and film being everything, it now feels like film is a conjuring trick. It's like, "Oh, my god, how are you going to do that in 90 minutes, as opposed to eight hours?! I've got so little time to do this!" It becomes an art form, in itself. Doing both helps you do each one.

I wouldn't put myself in that bracket, but it's one of those things. I think what helps is that we [with Tom Hardey] don't socialize, we don't really know each other, we purely work together.

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.

True stories are always good because they're so odd, and so unlikely.

I don't think that jealousy and love and hate and anger and all those things have changed in the past 200 years - people just express themselves differently.
