unfortunately i won't be able to do anything like that for the exterior in those top shots. The ground is moving very fast and i would have to build a very long set to replace it in order to have new AT-At's . but the displays will be having a tweak.

Ady. I took the frame from a next shot just before we see from the top the smoking speeder zoom out.

That particular scene have much motion and movement and you dont have to worry if the AT-ATs should look moving.

Plus the sun is changing all the time directions.

With several lasers and a slight motion blur you have your revisited shot :)

I can help you with the matte :)
