Heard a podcast over last couple of days which had what was being attempted with AI visually to something that would be analogous to this. Visually so a different sense but would mean that the indistinct person in the background could be a computer rendition of someone who would be in the distant past from when the film was made.
& quality of rendition unlikely to be kept high.
