That is acting being transferred from one face to another. I saw that when it first came out. Quite impressive.
But this neural net technology goes one step further - you could shoot a film with completely unknown actors, then the neural net can replace the real actors’ faces with millions of new, generated faces.
You might even have movies one day where YOU get to decide what the actors look like each time you watch the movie.
No more Brad Pitt or Scarlett Johansson in a movie. Instead generated Face #15388048948 and generate Face #58398782914.
You might get completely virtual celebrities like in the movie S1MONE acting in major films. (The Japanese already have those…)
