The fake Tom Cruise on TikTok, while not "photo-real" in any sense of the word, seems to overcome any uncanny valley effects through shear force of personality. We don't just observe the face, we react to the spirit behind it. In that case, the effects artist found "Vienna's foremost Tom Cruise impersonator" to provide the mocap. And then painstakingly mapped the face overlay to the emotional cues in musculature. And those seem to be the feature detectors we pick up on, rather than the highest fidelity.
