Just thought I would post some additional reference pictures of the Greedo subtitles from the 1982 Laserdisc, NJM posted one of these from the HBO broadcasted version earlier in this thread, the '82 LD uses the same transfer I guess. You can clearly see that it uses the same font as the original theatrical print if you compare them with the screen-caps on the first page, the lines are also broken up in the same way, just smaller with a different positioning due to pan & scan. I've also noticed that the Jabba subtitles in Jedi aren't exactly the same as the Greedo subtitles as I earlier thought, very close but not exactly, you can see that Jedi have smaller dots and some slightly different looking letters compared to SW, I assume it is the same font family just with a slight variation to it... I may obsessing a little too much over this but I find it interesting. ;) Just like how the "A long time ago"-preface differ slightly between the three original films.
Anyway, I intend to improve and update my sub-scripts located on the first page as soon as I get the time and the motivations for it, especially the Jedi script, if Video Collector's Jedi bootleg will shed some new light on the matter.
