I realize how much I rely on the actors to really know the lines because I tend to forget what they are exactly, even though I've written them. I don't have them memorized. But when it's going well, there is that point where the actor starts to know more about the character than I do.
You can be aware that something is idiosyncratic, and give it to a character, but keep doing it.
I don't agree with the idea that my characters are unlikeable.
I'm interested in music as an extension of character.
