Yep thats it, I was even briefly talking to the prop store to let us shoot on the original Nostromo model. But that never materialized.
I loved the model work, I know it doesn't stand up as well when compared to the other shorts with ship shots but we were always a slightly different production.
The model was about 4 feet, absolutely gorgeous too, it probably needed to be about 15 to 20 feet, but I knew we didn't have the cash/resources to make something massive-- we could've gone cgi but I really wanted the process to feel like making a movie in that era, that was important and just plain fun for me. So it wasn't just the final product that was an homage, but the production itself.
