5 golden rules for structure:

1. A screenplay doesn't tell the story at the audiences pace. CLARITY, CLARUTY CLARITY! audience must knowingly know they are being led somewhere worth while.Only tell the audience what they NEED to know and nothing else, do not bore them
2. SHOW DON'T TELL!
3. A screenplay is like a joke - set up, distraction, punchline 
4. Know your ending!
5. Count your "moments" - key great scenes that will be memorable
