One other thing I will throw out there.
From time to time, people gripe about the reversed, garbled foreign languages for Jar Jar, the Viceroy, and a few others.
I'm not particularly opposed to dubbing alien dialog over them, per se. Its just that the few times I've seen people dub into pre-existing films its been pretty laughable. If any voice actors want to volunteer and send me some voice samples at magnoliafan78@hotmail.com, I'd be glad to check it out and give them consideration.
