Does Jackson own the IP? Do actors own part of the IP for every scene they're in? What does Jackson offer to investors, to get the backing he needs to hire loads of horse riders or whatever? Do we do it Star Citizen style, giving Jackson a few hundred million upfront with no obligation to deliver anything?
On the other hand: if an artist produces something that slumbers in anonymity for decades before it suddenly explodes into popularity and becomes part of the cultural canon, then I'd want the artist to reap whatever benefits possible. That is: if anyone is making big bucks off of that, it first and foremost should be the artist, for as long as they're alive.
I'm against long term copyright, because things become part of the 'cultural canon'
Why should I pay George Lucas because I want to say "use the force luke"*
'Cultural Canon' shouldn't be owned by anyone, because it, by definition belongs to everyone.
