But it can't be accurate. Actors know that even micromovements tell a story and convey emotion. The computer cannot possibly infer enough about the person from a single photo to reconstruct that story. Were they a fidgety person? Were they tired that day? Bored? Impatient because they need to get the store before it closes and the photoshoot is taking a long time?
Imagine running this software on a photo of your parents. Do you think you would be impressed by the accuracy?
