I was born after 1981 and only knew the crawls with Episode IV subtitle. I remember I asked my father about the first 3 episodes but he had no idea (remember younglings that democratization of Internet only occurred around 1999/2000 for middle class people in France). Circa 1995 the first issue of the french version of Lucasfilm Mag was published, and there I got all the answers: “ok, they are going to make the missing episodes… oh and a new Indiana Jones movie as well !”. There also was the back of the french Laserdisc edition of TESB stating that it was the 5th entry in a Saga of 9, with 6 entries still to be done.
It was nice to be young /:
Now I’m older and the 9 movies exist. Man…
