Agreed, but because all of that should be public domain at this point. The idea that some company needs rent-seeking motivation to allow people to view 50-year old media literally until everyone who could have consumed it when it was published is dead is absurd.
Edit: You're right. Just disregard any laws and contracts in place. HN knows best. It must be that easy.
Under that, everything before 1985 would be free of copyright already.
I think the majority of Americans would greatly prefer that model; but, The Mouse had other plans and has extended copyright to approx 100 years.
We're talking about movies that are 45 years old at a minimum. The majority of the people "involved in making the film" are dead at this point.
