lol, nope, that would be way to expensive to do, because not only would you have to reanimate the mouth, but also the entire lower jaw.

The english script for perfectly synced voiced overs, are usually fairly different from direct translations, a good expample of this is many anime in which if you turn on english subtitles and english audio, you'll start to get really confused when what's being said doesn't match the subtitles except for maybe one or two words.
