I can't tell if you both are joking or not but watch the whole video. The source video is of Bill Hader. Bill hader's face changes to Tom Cruise everytime he talks from Tom's perspective. And then once to Seth Rogan for that impersonation.

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.

You’re correct. If you listen to what he’s actually saying it’s told from the perspective of Hader and it only shifts when he’s doing an impression of Cruise or Rogan.

Ah, I didn't listen to it with audio. My mistake!

As an aside, I feel really weird having completely convinced myself that the original video was deepfaked. It's kind of unnerving given the subject matter.
