SP FX: The Empire Strikes Back, Laserdisc, CBS/FOX Video. Japan, 1995
The Making of Star Wars, SP FX: Empire Strikes Back and Classic Creatures: Return of the Jedi were re-released by CBS/FOX video in Japan in 1995. These discs command a high price on the second hand market, but don't seem to be particularily rare.
This making-of programme and it's siblings was supposedly first released on 8" laserdisc in Japan. I've yet to corroborate this. I've found a previous version of Classic Creatures from Japanese distributor VAP Video in 1986, but not on the 8" format. The search goes on.
