Not being really able to tell if you are watching a clone, drone, double, masked actor, CGI, historical footage, or the real person is kind of liberating. You just ignore all the "noise" at the individual character level, and only focus on structural matters or issues of principle.
It is amazing people dont believe human clones are possible, I mean it was released to the public in 1997 they cloned a sheep, Dolly, so realistically they probably had it down pat 10 years previous to the public finding out.... if they can clone one mammal, cant be hard to clone another type...
