Travel back in time to Middle-earth with Amazon Prime’s upcoming TV adaptation of the popular classic fantasy saga The Lord of the Rings written by J.R.R. Tolkien. The story is set to take place during the Second Age of Middle Earth, with development still underway and key details still kept confidential.

Amazon Studios announced the adaptation of the series after Christopher Tolkien left as the Estate Director in 2017. Amazon confirmed they will focus on Dark Lord Sauron’s rise and the forging of the Rings of Power; both events taking place during the Second Age, long before Peter Jackson’s movie version of the The Lord of the Rings and The Hobbit trilogies.

Despite maintaining an active Twitter account and dropping hints here and there, we know very few important details about the show. The history of Middle-earth is divided into Four Ages with every age lasting around 3,000 years. Both the The Lord of the Rings and The Hobbit trilogies take place during the Third Age. The ending of The Lord of the Rings: Return of the King, we see Aragorn (spoilers) claim the throne of Gondor… marking the beginning of the Fourth Age. The TV series will more likely be a prequel to these events with new characters, and location.

As posted on their Twitter account, screenshots of a map showed the kingdoms comprising the Middle-earth. Alongside the map, excerpts from the Rings of Power have been used as captions.

Back in 2017, Amazon reportedly paid $250 million for the acquisition of global television rights, hailing it as the most expensive TV series ever. It is expected to have 5 seasons as part of the deal. The whole budget for the show is speculated to run more than $1 billion. Filming will begin in August in Scotland, targeting to hit the small screen on 2021.
