OK I have an on topic question for Ady.

Sorry if this has been covered before but I am interested in the process you are using to do this revisit. I understand you are redoing the asteroid canyon and are building a canyon so that you can refilm it. Presumably you aren't going to redo the TIE fighters, but what exactly is involved? I guess it is along these lines:

1: Use photoshop (or similar) to isolate the existing TIE fighters, falcon and explosions from the background.

2: Shoot footage of the new canyon and paste it into the background of the isolated spaceships.

3: Do some photoshop magic to make it all seamless.

I am sure that that alone is a huge job but is that more or less the right idea or are there some extra steps involved?

Secondly, what is wrong with the existing canyon shot? I can't see anything myself but I have not studied it in the detail that you have.
