When it comes to structure, don’t be too repetitive when it comes to your writing
Have more than one story and make the stories parallel with another
Go back between stories. Once one story loses interest drop it out for the other to maintain the quality of the story
Efficient actions lines (serving as a guide for the actors/director) can quickly set the tone of a scene
Dialogue may change from the screenplay to screen because of adjustments from the actors or the director, making it important for the writer to set the tone for the scene
The first line of dialogue in a scene should essentially frame the rest of the scene. While the last line should be the point of the scene
Subplot characters can be used as a device to reveal (new) information to the main character
Subplot characters can also be used as examples of what can potentially happen to the main character
Writers need to be clear, concise, and creative when preparing a screenplay
