Middle Earth is coming to TV.

Amazon announced on Monday that it has retained the rights to adapt J.R.R. Tolkien’s “The Lord of the Rings” for television for its Prime streaming service. The multi-season adaptation will feature “new story lines preceding J.R.R. Tolkien’s ‘The Fellowship of the Ring,’” which is the first “Rings” book, Amazon said in a statement. The deal also includes the opportunity to pursue spinoff series.

But it will cost Amazon dearly: Deadline reported that just the rights to the globally popular franchise cost $200 million. Further details — such as what writers, producers or actors would be involved, or when the show might debut — have not been announced.

With its fantastical setting and characters, “The Lord of the Rings” bears a superficial resemblance to HBO’s “Game of Thrones,” currently one of the biggest shows in the world. (George R.R. Martin, who wrote the books that series was based on, has said Tolkien’s series was an inspiration.)
