Once I got over the fear of writing female characters, it actually came quite easily and I was really happy with it. I just thought about girls I knew really, really well and I'd just have conversations with them and tried to relay how they talk about certain things.

As a director, you have to know what actors are doing. You're the one telling them what to do. The actors' job is to come prepared to the set, but sometimes, if they're beginning actors or people who are non-actors, you have to teach them how to act.
