As technology progresses, it seems like only a matter of time before all photos and videos can be perfectly modified to suit whatever purpose. At some point, perhaps movie stars will do no more than lend their likeness (airbrushed of course) to productions.
It will be a case of '3d killed the video star,' in many ways. We are already approaching a point where the acting and the appearance are two different things; actors like Andy Sirkis and Doug Jones are not very well known to the general public, but have played starring roles as larger-than-life monsters of the screen. Although it is not yet economical, it is already quite possible to take one person with excellent acting ability and map on the appearance of someone else who is more visually appropriate or attractive.
