HOLY SHIT. Love the way Caesar incorporates his signing with his spoken language. And is that an ape in a wig made out of twigs?!
Thanks to rdeckard for alerting me to this new trailer.

On a more serious note, the shot of Caesar watching the home video footage reminds me of real life, ape language ex superstar Nim, in his final home, a cage on a ranch, wistfully looking through a tattered old copy of Time magazine at images of his childhood and human family.
