100 Years is apparently a short film. Rodriguez stated in a 2019 interview:
I was making several short films for them, and I finished that one first, we shot that one first, I thought that was gonna be a commercial or something. And then I showed them the movie and they said “Yeah, that’s great, that’s great. That’s the one we lock away.” And I said, “What? That’s the one you lock away? What about the other one with the future…” “No, that’s the commercial.”
I found out while watching an Interview with Claudio Miranda and after that checking his Filmography section on Wikipedia
Well if you’re born in 1877 in a world of telegraphs and steam engines and got to live a hundred years and see Star Wars I in the cinema I think you’d have a bit of an epiphany about how much the ability to fantasize about the future has grown over your lifetime.
Star Wars wouldn’t have been worth a 100 year wait.
