Keep Dialogue in Character

My dialogue is precise. And it’s true. I think out the truth of what the people are saying and why they’re saying it. Dialogue comes because I know what I want my characters to say. I envision the scene; I can imagine them up there on the screen; I try to imagine what they would be saying and how they would be saying it. And I keep it in character. And the dialogue comes out of that.
