Producing a movie like Star Wars requires the collective effort of thousands of people including writers, artists, designers, camera operators, computer engineers, editors, and actors. Furthermore, movie sets require resources like lumber, paint, lights, props, and cameras. Use the idea of the invisible hand to explain how these workers and resources are organized so effectively without government planning.

All the people involved in the production of the film try to do their best because they are motivated by self-interest.

This self-interest is represented in two ways: the need to make a living, so they work effectively in order to be paid instead of being fire, and also, self-interest is represented by desires of fulfillment, which tend to be specially common in artistic enviroments. The director wants to do his best because he wants to feel personally accomplished, same for the script-writers, the actors, and even the make-up artists.
