I need to know more about charachter motivation, I know that in each scene a charachter needs to have a motivation as well as a goal for the entire movie. I know the roles of each charachter, the protagonist, antagonist, best friend etc. But how do I smooth these into scenes. I want my scenes to flow and make my actors lines to seem natural and for each scene to contribute to the story, but also not to be redundent in these scenes. Are there any links that could help or any advice anyone can give me?
