Here's how old Elrond is in Amazon's The Rings of Power TV series isn't blessed with a huge selection of familiar faces. The few returnees include Galadriel, Elrond, Gil-Galad, Isildur and Elendil, while Sauron will inevitably rear his head sooner or later also.
Lord of the Rings fans will Elrond as the majestic Lord of Rivendell, a member of the White Council alongside Galadriel, Gandalf and Saruman, and a powerful leader among elves. Tolkien's original book and Peter Jackson movie trilogy both depict Elrond in this regal light, but his status is very different in The Rings of Power. Played by Robert Aramayo, Amazon's Elrond is an up-and-comer in elf politics, mentored by the High King of the Noldor, Gil-Galad. Elrond isn't a leader in his own right just yet, and doesn't become a father until the Third Age. Because Sauron is yet to resurface in Middle-earth, Elrond isn't even the seasoned warrior he'll become by the time the Second Age ends.
Elrond the half-even is born to Eärendil and Elwing in year 532 of the First Age, which ends in 590. Elrond and his brother, Elros, are given a choice between their elven and human heritage, with Elrond choosing the former and Elros the latter. The Rings of Power are forged around year 1500 of the Second Age, which means Robert Aramayo's character should be approximately 1558-years-old during Lord of the Rings: The Rings of Power. Alas, the calculation isn't quite that simple. The Rings of Power will condense Tolkien's Second Age from 3000+ years into a single point in time, so there's no direct year-to-year comparison between Lord of the Rings mythology and Amazon's TV series. Either way, The Rings of Power's Elrond will be considerably younger than the elf who welcomes Frodo into Rivendell at a spry 6497-years-old.
Can Hugo Weaving Appear In The Rings Of Power?
The more Amazon reveals about The Rings of Power, the less likely appearances from the 2000s movie trilogy cast begin to look. In theory, you could say Robert Aramayo is playing a younger version of Hugo Weaving's Elrond. Hypothetically, Hugo Weaving could then appear in flashforwards or narration sequences. But The Rings of Power is increasingly distancing itself from Peter Jackson's Lord of the Rings movies. According to director J.A. Bayona (via SFX), The Rings of Power was initially designed to correct directly with Jackson's movies, but this changed halfway through production. Bayona its, "the more we were working with the characters and the story, the more we were unconsciously disconnecting from the movies." With this in mind, if an older version of Elrond ever does appear in The Rings of Power, they'd likely be portrayed by a completely different actor (or Robert Aramayo with a bit of make-up, since elves are immortal) instead of Hugo Weaving.
The Rings of Power may not have a choice but to separate from The Lord of the Rings on the big screen. In The Fellowship of the Ring, a flashback scene shows Cate Blanchett's Galadriel alongside Mark Ferguson's Gil-Galad receiving the Rings of Power. Assuming this moment happens in The Rings of Power, the characters involved will look completely different. At that point, the ship of bringing back old faces would've already set sail from the Grey Havens.
