Face retouching in film
Retouching films is nothing new in the digital age. As early as 1993, faces were subsequently replaced by others in Steven Spielberg’s film “Jurassic Park”: back then, a stunt double accidentally looked into the camera, the face was replaced by another in post-production.
But a short sequence is different from a whole film. Here the hurdles are much higher, which Solutions Lane online in the article on the Deepfakes makes clear. In principle, however, faces in videos can be replaced by those of living or deceased persons. Accordingly, it has already been discussed whether the deceased actress Carrie Fisher will continue to be seen in Star Wars as Leia with the help of face swaps.
