Reading Easy Riders, Raging Bulls atm and there's a bit where Biskind mentions people like Hackman being cast in Bonnie and Clyde as a point at which people who looked like 'real people' started to make their way into Hollywood.
Will we see this again? If we operate in cycles it's inevitable, but society seems more image conscious than ever these days and cosmetic surgery's becoming increasingly common, so maybe 'real people' will eventually just look like movie stars?
I suppose if we get to that point the distinction will simply be how good your surgeon is.
