Social media is probably our best bet in 2017.
Is there an original trilogy facebook page? It might be worth it to create a page and then you can run a newsfeed ad. You can target only people who like pages related to Star Wars, and I would narrow it down further to people over the age of 35 or maybe even a bit older as that is still a lot of people.
I just checked and there are currently 8.2 million people on facebook in the US who are over 35 and specifically like Star Wars pages.
