First and foremost, one way or another, get a copy of this DVD NOW!!!! Even if it means getting on a plane, flying into Stanstead Airport UK and crawling on all fours northbound along the M11 Motorway and calling at every city, town, village and hamlet until you find Mr JD.
If you were after Deleted Magic for Empire, this DVD is not it.
If you were after Sith Revealed for Empire, this DVD is not it.
If you were after Star Wars from the Film Vaults for Empire, this DVD is not it.
However, it does combine elements from all three.
Building Empire is not a film, not a documentary and not simply a commentary either.
"What the hell is it???" you ask.
It is a combination of the best bits of all of the above done in such a way that you could watch it in place of the actual film or as a documentary/commentary as it works both ways.
I could waffle on for hours but there is no point. Just get a copy and see for yourself.
The equivalent title for Jedi is in the pipeline and I cannot wait to see that. As it is done in such a different way to Deleted Magic and others, I also hope to see a Star Wars version done in exactly the same way.
