I've been wanting to make a thread like this for awhile, but it can be hard to explain the concept, and also to tease out its referents. Sentences, designs, etc, utilized in one film (or other art object) can point to other concepts in another. As Lucas said once, "they rhyme." What I find interesting about reference like this is the way it can pull along (or generate) expectations and inferences that aren't directly stated. The throne room scene at the end of ANH deliberately echoing Triumph of the Will is one example. There are many. (You might say that the commonality of many prequel speculations by OT and Intertrilogy-era fans could be another example. People picked up on the way things were stated, the language used, and drew the simplest plot assumptions from that - often, these are close to the actual intended directions of the story at that time (as far as we can tell).) I started this thread now because I'm reading Vonnegut's Slaughter-house Five, and I came across something Yoda would later say. "There is no why." I had also earlier noticed, while looking something unrelated up on Wikipedia, that the term "luminous beings" seems like it could very well be a reference to "luminous minds" in Buddhism. Both of these in their original usages appear in contexts seemingly congruent with how they're used in the film. I don't know if these are intentional references, but it sure seems like they could be. How many others of these are there? Have you noticed other references to other films, artworks, books, philosophical concepts? Do we think this says anything about the writers intentionally trying to create implicit messages to viewers who get the references?
