Thanks to ben_danger I've seen the workprint now!
As someone who was skeptical of Trooperman's voice for Anakin due to what I'd seen in the odd preview clip, I have to say now that I think it's actually spot on. There are a few bits of poor lip-synching here and there but otherwise I thought it was a great improvement over Hayden.
Not so sure about the replacement Jar-Jar voice since he really does sound very different to the original. I couldn't even tell any of the other characters had been dubbed, the quality is that high.
Well done all round, and I look forward to the even better final version!
