hmm i think the redubbing of hayden sounds risky too - and sounds like you are making a lot of work for yourself - but, you have to do what you wanna do - its definately a very different type of edit than ive seen so far - so i hope it really works out for you
All i was gonna say originally, is that the way all the people talk in the prequels sounds flat - the conversations never seem to flow naturally, which leaves me feeling a bit....uncomfortable is the only way i can describe it.
I saw bobgarcia's edit of the opera scene in reign of the darkside and was flabbergasted! the conversation now flows really naturally and almost seems like it was meant to be shown that way - I cant stand to watch the original version cos it just makes me go into spasm's. So i was much relieved watching the edited version and enjoy'd the scene.
but the time it must have taken to do all those small cuts and move things round and still have it spot on must be a nightmare. So wether you try something like that to concentrate on improving the flow of conversation or just re-dub...it all sounds very complicated!
may the force be with you dood!
