About three years ago Amazon announced a TV adaptation of J.R.R. Tolkien's The Lord of the Rings, and now we have the official official show synopsis:
"Amazon Studios’ forthcoming series brings to screens for the very first time the heroic legends of the fabled Second Age of Middle-earth’s history. This epic drama is set thousands of years before the events of J.R.R. Tolkien’s The Hobbit and The Lord of the Rings, and will take viewers back to an era in which great powers were forged, kingdoms rose to glory and fell to ruin, unlikely heroes were tested, hope hung by the finest of threads, and the greatest villain that ever flowed from Tolkien’s pen threatened to cover all the world in darkness. Beginning in a time of relative peace, the series follows an ensemble cast of characters, both familiar and new, as they confront the long-feared re-emergence of evil to Middle-earth. From the darkest depths of the Misty Mountains, to the majestic forests of the elf-capital of Lindon, to the breathtaking island kingdom of Númenor, to the furthest reaches of the map, these kingdoms and characters will carve out legacies that live on long after they are gone."
interesting reveal, to be sure. Per this synopsis, I would guess that the show will take
place during the 2nd millennium of the Second Age, covering the forging
of the Rings of Power, the War of the Elves and Sauron, the Sack of
Eregion and the Founding of Rivendell. They ought to bring back the movie actors of Galadriel, Celeborn, and Elrond for this. Maybe even Gil-Galad.
"We have reached the borders of the country that Men call Hollin; many Elves lived here in happier days, when Eregion was its name." - Gandalf
