Historical Video Gesture Dictionary

Did you ever notice that you can date a movie by the facial expressions/gestures of the actors? I just watched an Andy Warhol film that made this clear. It was a series of 3 minute clips of celebrities mostly staring at the camera and trying not to blink. As I was watching I was thinking that the celebs could have been from 2005 because all they were doing was blinking and that is an undatable gesture. But some of the celebs were mugging and it became obvious right away when they did, that they were from the 1960's. You could see that they had copied their facial expressions from people around them and that those kind of gestures -- that language is one that changes quickly over time. and i also decided that I want my own gesture vocabulary to be totally composed of timeless gestures. Or is the timelessness just about a lack of self-consciousness?

anyway it would be good to have a video dictionary, now that there is so much available web video, of gestures and facial expressions by chronological date, with examples from the movies of the era.
