"What makes a good movie?"
Three stages of production- PreProduction, Production, Post Production.
PreProduction = script, storyboards, location scouting, hiring cast and crew, generally the plan for the production.
Production = shooting, directing, sound recording, acting, etc. all things created following the plan.
Post Production = Editing film and sound. Adding special FX, scoring, foley and so on. Creating the product from the previously produced pieces, but always following the plan.
What makes a good movie? A great plan that follows a tight schedule.
