Here's the Japanese version of the Star Fox Assault Fichina Briefing scene. As usual, the characters are more expressive, especially Fox. Here, he has a genuine look of surprise at one point, and in another, a silent laugh. Both are completely absent from the English version.
Now, let's combine the Japanese animation with the English voice acting and text. This time the lipsyncing mostly ok.
I also noticed that in the English version, Falco speaks some of ROB's lines.
