Imagine though a world where copyright is at most twenty years under special cases, ten years by default...

» Nobody is going to pay for the rights to the Hitman video game franchise and create The Professional. Because if you mutate the story that much you’re legally in the clear.

We would see new movies using footage from existing twenty year old movies maybe even a different cut of not so old movies.

I think age of five years for patents and twenty years for copyright is the maximum I can support.
