So I had a thought, as I'm seeing all these exciting PT edits coming along. The redubbing is especially fantastic, and I hope that some of these folks will share notes and their dub tracks.
Along those lines, the Neimoidians have been repeatedly criticized for sounding like Asians (or one sounding like a surfer). Some have tried dubbing with Japanese or reverse Swahili or something, but I think it would be best to have a more foreign sounding language.
Star Wars lore now states that they are related to the Duros, those blue guys you see in the Cantina in ANH
Duros
Neimoidians
I think it might be interesting if someone could create a track of some vocals similar to that of the Duros and dub the Neimoidians with that. That way well designed dubs could fit the mouths better, wouldn't be interpreted as racist, and could allow for a more purposeful Federation rather than silly, cowardly, pointless Sidious puppets.
