For the novelizations of Star Wars: A New Hope, Alien, Aliens, and Alien 3, as well as for his novel, Star Wars: Splinter of the Mind’s Eye, Alan Dean Foster is supposed to be receiving royalties. He doesn’t get copyright control of the worlds and characters of the Star Wars and Alien franchises, but he is supposed to be receiving royalties for the books that he wrote for the franchises.

And he did receive them… until Disney bought Lucasfilm and Fox, thus buying both the Alien and Star Wars franchises.

Then, the royalty checks stopped.
