The Saul Zaentz Company currently owns rights to the universe and characters created by J.R.R. Tolkien or almost all of 'em, anyway and has since 1976, but it's now reportedly ready to sell for at least $2 BILLION This might sound a little confusing, because as you know Warner Bros. (through ownership of New Line Cinema) made Peter Jackson's enormously profitable 'Rings' trilogy from the early 2000s, and 3 'Hobbit' films in the 2010s.
Amazon is getting ready to roll out its "The Lord of the Rings: The Rings of Power" series on Prime. SZC has been battling WB over its share of profits from the 6 films, and reportedly believes it's reclaimed the movie rights because WB hasn't developed any new projects since 2014's 'Battle of the Five Armies.'
