Building Empire is a really nice DVD!
I would discribe it as Directors Commentary Voice with many EXTRAS
I really liked the Comic Strips putted in!
Or the Scenes where you see the Rehearsals.
And the Interviews with the Actors Id never heard bevore, except the ones from the 2004 DVD!
Must have been very hard to collect all the Stuff.
So my final word:
I cant wait for Returnig to Jedi
