I don’t know if a precident has been set yet, but training is legal and the work is not a copy, but a derived work, so should be fine.

Can’t use the trademarked terms and whatnot, but creating things in the style of seems legal.

It’s like reading Tolkien books for 1000 hours and then writing a book that’s inspired by Tolkien.

Or like making a painting in the style of Picasso, etc etc

I think you're thinking of “transformative”; a derived work is by itself still subject to the copyright of the source material.

This is a common misconceptiom.

"Derived work" does NOT mean "copyright of original does not apply".

It means "copyright of original DOES apply, in addition to copyright on the modifications."

Lord of the rings is a good point. From what i understood this is a very difficult terrain to manouver leagally. Why is Disney so passive? I cannot imagine this to go on much longer.

Apart from the words "Star Wars" in title this is clearly a derivative/inspiration, not a copy.

Oh sure- try and make a sci-fi movie with anything vaguely resembling a lightsaber…

I think that’s more due to cultural uniqueness than legal restrictions.
