Idea Brainstorming

Start with hook and logline which is actually pointing a unique situation - which is a high concept.

Example

Example of Logline from Wikipedia

• There's situation, concern and interestingly want to know further
• It's a situation, not a story but it promises a lot!

Faults in Developing the Idea

• writer takes the situation into predictable or familiar direction
• writer trying to avoid the predictable and lead the story to different way and drop the early promises
• writer comfortable with writing in specific genre and style; and can't change into other groundwork/genre

Tips on How to Make Idea Works

• Change the perspective from other person's point of view -- explore the reaction, emotion, etc.
• Decide at which point the story start -- ie. start with tragic incident
• Change the protagonist undergoes -- films there’s a “character arc.”
