even with clear HD video I have no idea how this is working

I need someone to explain 2 me the magic, I'm loosing sleep over it

It's not just a puppet.

Oh shit it's hogart

The face is heavily cgi in post processing apparently, but the puppet makes it a lot easier

Is this for a live Iron Giant play?

I HAD to edit with the movie (it's a bit wonky but it work)

That’s cgi and stop motion on top of a puppet.

I honestly thought the puppet's hands were human-operated (akin to the TV show Spitting Image) when I watched the low-res video. Man, puppetry has come SO FAR! Can't wait to see what this production company does with Dynamic Duo.
