In a decade or two computer power will rise to a level that will allow a rebuild of the original film. It could be rendered in 3D and widescreen. It could even be rendered as a virtual interactive environment. Sets could be altered while leaving the original actors untouched. I say hold off on remakes until they can be done properly.
Sometime around 2025 all that will be needed to create a film/3D/virtual environment will be a script and a super computer render farm...actors no longer required.
...followed by virtual paparazzi
I have been saying that for years.
It IS possible NOW.
We could actually bring back actors from the dead, using computer graphics.
Bogart, Flynn, Gable, Wayne, Davis, Hepburn, all the old time actors can be recreated and their voices synthesized................Three Stooges...........
