So how far are we from a scripting software that allows you to describe a movie and then it renders it for you?

Like you describe the scenes:

“A Jumbo Set is landing in LAX in 1987 at dusk, the sky is orange from pollution.”

Scene 2

A balding, brown haired 45 year old police officer called John Mc Clane is clutching arm rest with a ring in his finger.”

Then you write a dialogue and later you can just refer to people in words and it remembers them. Then you can render it all to a movie.

Possibly with a option of doing re renders just by describing what you want changed.

Of course the resolution could be low on the initial renders.
