We've had a recent breakthrough on the possibility of doing Dooku as a hologram in front of the Jedi Council, thanks to tjdavis1138. Without tipping our hand too much here, the plan is to use old Hammer Horror footage of a slightly younger Christopher Lee, process it as a hologram, and edit it with Lee dialogue from other films, intercut with reaction shots of Yoda, Mace, etc.
Sorry that the new Neimoidian dialogue will ruin your experience of The Passion, but so far this method has worked extremely well. Although it's not set in stone. "Audio morphing", I'm afraid, might yield the same results as MagFan's edit. I'm actually in talks with an older Greek gentleman I know who has some acting experience and may be interested in translating the Neimoidian script into Greek and recording the dialogue. He's got a great, deep, intimidating voice! Similar to the guy in the Passion. I just wonder if Greek is too recognizable a language. To me, it sounds alien, but to someone who is familiar with it...
On a seperate note, Hal, for some reason I feel indebted to you. We've talked in the past, either you sent me something or I sent you something in the mail. But I haven't seen your name pop up on here in a long time. You might've sent me my Darth Editous edit. If that's so then thanks again and I still owe ya one!
