4:50 Monkeys can’t do art. “I want to convey an emotion to another human being that’s something only human beings can do. Animals can do it by roaring in your face or biting your hand off and that usually has an effect, but to do it in a painting, to do it in a play, in a story, in poetry, or anything that’s in the arts, you have to be a human being.”
Reference The Abolition of Man by CS Lewis.
The irony of course is that in the prequels especially Lucas wants to do more than “convey and emotion” but this system won’t allow him to admit it. He wants to use art to show “how the world IS” but he can’t admit it.
