What would happen then if someone wants to make a movie about a book published a few centuries earlier? Would they have to do deep archaeology to find the heirs of the author, the heirs of the heirs, the heirs of the heirs of the heirs,... and then get permission of the hundred-odd heir^Nths?

The law would obviously need to address such scenarios. One idea could be to also make everything public domain, for all mediums, when the author dies or a certain period has passed (like 70-80 years).
