The movie was made before he knew it was the one that would be locked away.

100 Years is apparently a short film, Rodriguez having stated in a 2019 interview with French YouTuber InThePanda: "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.' [...] The one that I was most attached to was the one they locked away."
