You might be right there. It does make a kind of emotional sense. And the climactic moment in Coppola's film where the Senator is changed back to a white man from a black man is very moving. The camera follow the Senator in a single shot as the world itself turns from nightime to daylight on what looks like an outdoor location. I don't know how Coppola did it, whether it was done inside the camera or in the lab, but it's exquisitely done.
