The best part about this is that I might be able to extract Portman's dialogue from the center channel and... use the same process on it. That would REALLY sell the two voices as being in the same space....
I'm excited about this all over again. Using this technique will put this edit on a whole new level. And the great part is that I will have the actual video footage on the film completely finished, encoded and in my DVD player by Christmas. The one or two months after that will be spent reprocessing the ADR recordings in the way Adywan described and mixing them back into the picture.
This was the exact problem, see. I was recording very closely to the microphone, and to compensate I was trying all kinds of things, from lowering the bass, to adding filters, to adding a bunch of artificial reverb to match the surroundings atmosphere. And although I never admitted it to myself, it wasn't working a lot of the time. Using this technique will make it sound like Hayden always had my voice, and as Adywan said, it will add a much more natural reverb to the sound.
Thank you so much, Adywan. I'm kicking myself for not realizing this sooner, but I'm also really, really happy now because:
1. The movie is practically done. My dream of watching a brilliant version of Ep. II is about to be fulfilled, and
2. Now I have a way to make this the way I always wanted to have it- the newly recorded voices will be integrated seamlessly.

Adding new English voices recorded by fans to a 2002 feature film like "Attack of the Clones" is so difficult- I know why nobody's attempted it before. But it's being done now.
My recommendation now is to just completely forget that this even exists until next year. It'll make the wait less painful. In the meantime, I'll be working on something designed to knock all of your socks off.
But for now, I'll be taking a little break and having Thanksgiving with the family! Happy Thanksgiving everyone!

P.S. Does anyone know anything about where to find that ratings card I posted earlier?
