Small note: When George Lucas decided to expand the Sequel Trilogy from one film to three (as mentioned in The Making of ESB), he initially considered having each film use the same cast and script, but different directors.
That way, by experiencing the same story three times in different ways, audiences would see what a director’s sensibility brings to a film: a particular point of view.
Too bad directors don’t direct the film anymore. It’s now a soulless, corporate, machine.
