I honestly can't see much change in the face throughout the video.

It probably doesn't help that I am so horrible at celebrities that I couldn't picture Tom Cruise or Bill Hader in my head if I tried, nor do I know what they're famous for. I just know that Tom Cruise sounds familiar and everyone seems to act like Bill Hader is significant so I go along with it.

I guess there's a some change in the face when he switches "voices". It's not nearly as exciting as the one of Obama saying stuff he's never said before though.

If you know Bill Hader's face, the change to Cruise is pretty obvious. The Cruise resemblance is subtle but strong.

Part of the point with fakes like this is it's not just gluing a head on someone else's body, like a bad photoshop. It's actually changing the facial features of the target to resemble someone else.
