I think SOME Dune footage really works to open the battle up beyond the original mass of missiles going -----> and then <-------- and then >x<!! In its current form, with ID4 elements in there too, I think the whole battle isn't quite what it will be.

Transforming that battle into something coherent is like taking hamburger and trying to reshape it into a cow.

I think finishing the battle (without getting into shot-by-shot advice) might be a matter of "less is more". When the one trooper says "this battle is over before it's even begun" I think that says it all. Then the clones can demonstrate their ass-kicking ability and we move on. That's about all the coherent information available in all that footage. Everything else is just cg weapons blowing each other up.

All we really care about at that point is getting Dukoo.
