Every once in a while, I come across someone who thought Peter Mayhew did the wookiee sounds for Chewbacca, or something like that, when in actuality those sounds were create by sound designer Ben Burt in post-production. As a kid, I even thought the actors in the Jawa cloaks were the ones making those Jawa sounds! All this got me thinking, has there ever been a case of the person in the suit also supplying the sounds for the creature/character they portray?
IMPORTANT NOTE: I'm asking about creatures/characters who don't have a lot of (english) lines, like Chewie. We're talking grunting, roaring, hissing, or strange, exotic languages like wookiee roars, so Jar Jar, Dobby, C-3PO, Yoda, and Unkar Plutt don't count since they speak "english" a lot. I'd say if they have more than 10 to 15 lines of normal (english) dialogue, then they probably are not what I'm looking for. Also notice that by "inside the suit" I'm including CGI motion capture characters.
Example answer 1: The puppeteer who worked Jabba's mouth also spoke the huttese lines on set (and maybe later re-recorded the lines in post-production) [Disclaimer: I made that up!]
Example answer 2: The guy in the motion capture suit who provided the movements for Sebulba spoke the huttese lines (and maybe later re-recorded the lines in post-production) [Disclaimer: I made that up too!]
Example answer 3: The guy in the motion capture suit who provided the movements for King Kong also recorded Kong's many grunts and breathing etc. in post-production. [Disclaimer: I made that up, I have no idea if that's true!]
