I'm not saying it can take the places of the most creative stances, only those who only follow orders. Every day AI technologies get cheaper while movie industry is one of the richest. I'm not saying that if you would put in it a lot of Tarantino movies you would have a Tarantino bot. What I am saying is that you could feed it with Harry Potter excerpts and it would create the most reliable Harry Potter face possible,way closer than Daniel Radcliff's. If you have technologies that simulate the movements of the human body you wouldn't need an actual human to act as Harry Potter, instead a digital Harry Potter. During fights agaisnt monsters he could be actually wounded without cutting scenes or VFX editions
