The Lord of the Rings: The Rings of Power brings a multitude of new faces to the lands of Middle-earth, with many familiar actors taking on the roles of some of J.R.R. Tolkien's most iconic fantasy characters alongside a number of unknown figures from the literary franchise. Their untold stories unfold across the Second Age of Tolkien’s coveted world, some 3,000 years before the events of The Lord of the Rings. From Men to Elves, Dwarves, Harfoots, and more, The Rings of Power introduces a staggering array of heroes and villains with parts to play in the fate of Middle-earth.

Prime Video’s Lord of the Rings prequel series has built up high levels of anticipation, awe, and fear through its marketing campaign. The Rings of Power's trailers and posters offered promising looks at showrunners J.D. Payne’s and Patrick McKay’s vision for the beauty of the Second Age, the forging of the rings of power, and Sauron’s subsequent rise to dominion.

The characters inhabiting Tolkien’s world are as integral to a faithful adaptation of Middle-earth as its visualization. Keeping track of who’s who can be tough in a work with as many names as this one. Here’s a guide to the actors who make up the cast of The Lord of the Rings: The Rings of Power and descriptions of the characters they play.

Morfydd Clark - Galadriel

Morfydd Clark's Galadriel submerged in water in The Rings of Power.

Morfydd Clark, whose previous work includes starring roles in Saint Maude, Crawl, and The Personal History of David Copperfield, leads the series as Galadriel, the legendarily beautiful Elf who goes on to wear a Ring of Power. Clark’s version of the iconic character is a rebel and a warrior, armed for battle. She’s a very different Galadriel in The Rings of Power compared to Cate Blanchett’s in Peter Jackson's Lord of the Rings movies, and it will be fascinating to see how the showrunners connect these two seemingly disparate portrayals of the character.

Ismael Cruz Córdova – Arondir

Arondir, a new character introduced for The Lord of the Rings: The Rings of Power, is played by Ismael Cruz Córdova. A Silvan Elf, or Wood-elf, Arondir is in love with Bronwyn, a woman from the village of Tirharad. The actor's prior work includes recurring roles on The Undoing, Sesame Street, and Ray Donovan.

Isildur is widely known as the Man who kept Sauron’s ring and set the stage for the events in The Lord of the Rings to unfold, but in The Rings of Power, he has not yet become that person. Maxim Baldry, who has acted in Doctor Who, Strike Back, and Rome, plays Isildur as he progresses toward his fateful decision on Mount Doom. He and his father, Elendil, hail from the kingdom of Nûmenor, though unlike many other men from their home, they have remained faithful to their longstanding Elven allies.
