We're at the point where anyone who's been photographed from a variety of angles (video definitely counts) can have a reasonably accurate 3D model of their face generated. Bodies are much less important to get the details exactly right on, so that model can be slapped onto an approximately correct one and nobody's going to notice the difference. Peter Cushing never had a detailed 3D scan done, for example, and they did a pretty good job resurrecting him for Rogue One. We can do even better now.

I have no good ideas for what the laws around this stuff "should" be. Just pointing out that from a technical perspective the question of "consent" is quickly becoming almost irrelevant - you don't even have to tell someone you've made a model of them, and they have no way of knowing you did unless they see the results later on. Interesting times.
