> The length of time a copyright can be held on any IP has been continuously lengthened over the past 20 years, making sequels a more tenable venture for movie studios. Strictly speaking, it was lengthened once, 18 years ago, with the https://en.wikipedia.org/wiki/Copyright_Term_Extension_Act https://en.wikipedia.org/wiki/Copyright_Term_Extension_Act I don't know if copyright law is really all the important. The Mickey Mouse Protection Act extended corporate ownership from 75 to 95 years, but no one is making an Iron Man movie or not based on what they think revenue for it will be in 2091, much less 2111. Economics alone means that the NPV of 2091 revenue will be ~$0. I find much more compelling the argument that it's an attempt to de-risk an increasingly capital-intensive and high variance business.
