There's nothing worse than a director who feels more like a cop than a comrade, so I try to never give orders or create an environment where it's 'my way or the highway,' because actually allowing talented people to bring their originality and insight always brings more depth and complexity than if everyone has to do what you tell them to!
When I directed my first short - 'American Virgin' - I had no idea if I could actually do it. Like, I might just get onto set, have everyone look at me and just completely freeze and have no idea what to do. But pretty much the opposite of that happened. I was like a fish diving into the sea.
