Fantastic Films magazine? They did a lot of wild speculating back in the day between sequels. I need to find those and see if anything was on the money.
I can’t say anything about Fantastic Films, but I did find some speculations in the letters page of some of the Marvel SW comics I recently got. Those readers did sometimes have quite on-the-nose ideas about the upcoming movies.
I think it’s especially funny to read the fan reactions to the Han-Leia-Luke love triangle prior to ROTJ. This one fan in 1980 even speculated that Yoda’s reference to “another” was a nod to a possible child of Luke and Leia. On the other hand, one fan unintentionally suggested that they were siblings while complaining about a lack of romantic tension between the two in the comic series.
I lament that those letter columns don’t make it into reprints. Maybe they’d have to track these people down to get permission?
And why the heck didn’t I ever write them a letter demanding Jaxxon’s return? 😉
