Wow.
In the video, his rapid and dramatic range of emotions, trigger moods, facial expressions, body language and almost every other nonverbal communication are evident from the 46 second mark to the 30 second mark.
In that very brief period of time he runs the gamut of seemingly experiencing overwhelming sadness and desperation (sighing, slouching his shoulders inward, holding back tears, choking up) while talking about those who support him, to quickly switching on the signs of anger and resentment (shaking his head, stern looks, glaring at the camera person, forceful words) when talking about the people who don't know him.
All in 16 short seconds. That's pretty good (or bad) turn-it-on-turn-it-off action, IMO.
And the Oscar goes to.....
