It looks like the key in the ruling here was that the AI created the work without the participation of a human artist. Thaler tried to let his AI, "The Creativity Machine" register the copyright, and then claim that he owned it under the work for hire clause.
The case was ridiculous, to be honest. It was clearly designed as an attempt to give corporations building these AI's the copyrights to the work they generate from stealing the work of thousands of human artists. What's clever here is that they were also trying to sideline the human operators of AI prompts. If the AI, and not the human prompting it, owns the copyright, then the company that owns that AI owns the copyright - even if the human operator doesn't work for them.
You can see how open this interpretation would be to abuse by corporate owners of AI, and why Thaler brought the case, which was clearly designed to set a precedent that would allow any media company with an AI to cut out human content creators entirely.
The ruling is excellent, and I'm glad Judge Howell saw the nuances and the long term effects of her decision. I was particularly happy to see this part:
In March, the copyright office affirmed that most works generated by AI aren’t copyrightable but clarified that AI-assisted materials qualify for protection in certain instances. An application for a work created with the help of AI can support a copyright claim if a human “selected or arranged” it in a “sufficiently creative way that the resulting work constitutes an original work of authorship,” it said.
This protects a wide swath of artists who are doing incredible AI assisted work, without granting media companies a stranglehold on the output of the new technology.
I wonder could you interpret this as AI created movie script isn't copyrightable but the actual filmed movie is. That would invite some weird competition, like we've seen over the years with the copycat movies.

This first but I don't think that is how it can be interpreted like that. Looks like it comes down to how much human input was used to guide the AI in the works. The more the human guided the AI the more they have a claim to the copyright is how I read that. Not just all AI content cannot be copyrighted. Which IMO seems like a fair way to apply copyright to AI generated content.
The latter part is basically already handled - look at any film created from a public domain works, Shakespeare plays being a big example here. I would expect non-collectable AI works adapted to film to to be handled the same way. Though I suspect that to create any good movie script with AI you would need significant human input which could lean towards to script having a stronger copyright claim by those that guided the AI.
Yes , but let's say Marvel writes the next Avengers movie with AI. Somebody else could come along and make their version of it. They'd need their own characters though, because those are copyrighted by marvel comics.
