So now we can look forward to a comic or film in which Tintin goes around Marlinspike killing everyone, and maybe even uses Calculus' ultra-sound machine in order to blow up Brussels?
Well, yes - except that that will be quite a way in the future, if the US model is followed: Calculus, Marlinspike and the events depicted in
The Calculus Affair won't enter the public domain for several years, a good while after Tintin himself does so.
However, you could get to work on your action flick, for release in America in 2026, in which an Arnold Schwarzenneger/ Bruce Willis-type Tintin and his attack dog Snowy take on the forces of revolutionary Soviet Russia, zombie infested haunted houses and rabid bears (before returning to a warm welcome by the children of Brussels)... :-)

I never understood why copyrights had to end. The examples above make a case for them to be everlasting.
As
I said earlier in the thread, I have some sympathy with that position - I get that there is some merit in having works of cultural significance available to all (which appears to be the main argument for copyrights ending), but likewise, I also can't see why intangible property like literature and music don't get the same treatment as land and houses, which can be used to generate revenue in perpetuity (or indeed why land and property don't enter the public domain after a defined period, and get used for the greater good of all).
