The whole top half of his face doesn't move at all, only the lower half! So it doesn't show any emotions which is strange in a human. His eyes also look like they are almost pinned open.There is a real super focus on only the words he is saying. The face doesn't match the words psychologically! I first thought cgi, but who knows as it caught him swaying in the beginning which doesn't really match the rest of it! Could be like you said, mind control! These were my thoughts in random order, sorry if it doesn't make sense haha!
