Is the prostitute in Full Metal Jacket talking in Vietnamese because I can't catch what she is saying? It sounds like random mumbling and not Vietnamese. I was raised in a Vietnamese family, but can't understand what she is saying...
I tried looking for some information on the Internet, but I couldn't find anything on that. Is it really possible that Kubrick didn't check if the actors are speaking Vietnamese?
Here is the link to the scene:
Edit: I don't think she was not Vietnamese because the guy is talking to her in Vietnamese and it's easily understandable. So, it wouldn't make sense if she was replying to him in a foreign language.
