The pick up shots done in Tunisia were done during post production on Clones i believe so they would not have to go back again.

As for where it was shot i thought a good deal if not all was on set in a warehouse that used to be a rolls royce factory and they used green screen to shoot Vader's masking, Vaders NOOO and Frankenstein act, Vader the emperor and tarkin overlooking the death star.

The making of book really try to get into a sense of where Lucas wanted to take the direction of the film, a lot of ideas were not used many for the better.  But changing Vader's turn from being seduced by power to saving padme from dying was moronic.

The ending scene for Episode III was originally shot on location in Tunisia during production on AOTC, but was reshot in the studio on ROTS.

Crews were dispatched to various locales to shoot background plates for Mustafar and Kashyyk, but it does seem the main unit never left the studio.

The same as Crystal Skull.  Background plates were the new location shooting for the jungle scenes and waterfalls.  Though other sets the college, the restaurant/bar, new Mexico and Peru were real.  Or at least i think they were.

The clone troopers and pilots in Episode II and III were cgi using the actors likeness for jango and boba.  No stormtropper like suit of physical armor was made or used no actual human was shot playing those roles.

The precursor to the X-wing, Tiefighter ships were all cgi in II and III.  The stardestroyers or republic cruisers were all faked in cgi.  Well at least Hayden Vader's suit was real but he was too short to match Prowse height.

Whoa!  Tbone (finally) updated his site!

EDIT: I feel kind of dumb, but judging by the news section, I was always looking at the archive site without viewing the new one.

Well that's not true. It's true they never made any clone armor and their bodies were completely CG, but in ROTS when they had their helmets off it was Temeura's real head. I remember being disappointed in the theater at how poorly those shots were composited.

The radio controlled R2 Units (like the K9 units on Doctor Who) were notorious blooper reel material, so while it may look crap I can see the financial reasoning behind using CGI as much as possible from a cheapskate perspective but from an artistic perspective it was very dumb.

The OT era radio controlled R2 units sure but this generation's? Are there any real reports about that? The stuff the Artoo Builders club can build nowadays is pretty reliable and nuts.

It is actually quite amazing that the film even turned out as good as it is. I can't imagine actors having to act in the very "inspiring" empty room.

People always say that and yet some have been getting along just fine for centuries....

There's a single close up shot of Obi-wan climbing out of a pool of water before it transitions to a master composite shot. So it's possible that, if nothing else, that could've been a complete on-set shoot.

Being asked to play your emotional scene opposite a tennis ball on a stick is another matter. ;)

Theatre acting (at least to me) is very different than that in the film. I don't know how to put it... well in film the aim of the acting is to make it look like they are not acting while in theatre they do it in a way that it is extremely obvious that they are acting.

That and George Lucas altering the script on the day leaving you with maybe three minutes rehearsal time.

 

Wasn't Anakin falling to the dark side by wanting to save Padme a last-minute script change?  (in the original script he just wanted power).
