[quote name='guardian_owl']The thing which still blows my mind is the space battle in Return of the Jedi, to think they had to shoot each of those ships models indivdually and edit them all together.[/QUOTE]
A lot of the space models are repeats. They also employed the computer controlled gadtetry they started in the original star wars that allowed multiple passes of a single scene to be played EXACTLY the same each time (ILM apparently obssessed over getting this computer control done during the original star wars and got extremely behind. They ended up not using it in some scenes they wanted to, like many death star pass scenes).
My guess, while watching the battle inside the death star in Jedi (what I was asking about before) was that it was a combination of miniatures and mattes (not counting the ships, but those are just models by a blue screen). However, I'm wondering if they animated the mattes. Some look like they could have been drawn to account for a camera pan. However, others have the camera moving into the picture. Others, I'm not so sure about.
[quote name='bmulligan']borrow someone's original trilogy bonus disk to get these documentaries covering sets, sounds, and effects:
Bonus disc: all-new bonus features, including the most comprehensive feature-length documentary ever produced on the Star Wars saga, and never-before-seen footage from the making of all three films
"Empire of Dreams: The Story of the Star Wars Trilogy"
Featurettes: The Legendary Creatures of Star Wars, The Birth of the Lightsaber, The Legacy of Star Wars[/QUOTE]
I can't remember which of those I watched, but it didn't have a whole lot of technical data on many of the effects.
