Cute and well made job. I suspected that the video simply took a standard Nixon televised speech and used CGI to remake just the lower half of his face (thus the odd head movements even though his words and lips synced correctly, and if you look closely you can see that the lower part of his face looks somehow "cleaner" than the upper half), what stumped me a bit though was the audio. His voice sounds odd but recognizably his own, especially since Nixon had a rather unique voice. so I thought maybe they cut together words he'd said in different recorded contexts and digitally modulated the audio to construct a speech with an even tone, but no, they actually faked his voice, which impresses me more than the face CGI.
