My mentors were my editiors. You come from location work with a million people and questions, and you get into the editing room, and its two people.
I have come close to producing films. But generally by the time they hit the screen, there's about 50 people with producer credits, so what's the point. I usually find scripts I like with no money attached and take them to producers that I know and try to raise finance.
Now, people can watch the entire first series over a period that would probably take you a couple of nights.
Mostly, people watch their shows online and they watch them in a block. They don't have to tolerate the commercials, and they also don't have to wait another week. People binge watch. It's interesting.
