Adam B. Vary Senior Entertainment Writer Robert Aramayo had no idea when he first auditioned for “The Lord of the Rings: The Rings of Power” that the role he was vying for was Elrond, one of the most revered and crucial characters in J.R.R. Tolkien’s epic saga of Middle-earth. Hugo Weaving played Elrond in Peter Jackson’s trilogies of “The Lord of the Rings” and “The Hobbit,” and as a kid, Aramayo had been captivated by the films. So when “The Rings of Power” co-showrunner J.D. Payne told him that he’d been cast to play Elrond as a (relatively) young man, the now 29-year-old actor couldn’t believe it. “I had one of those moments where everything in your body feels like you’re on electricity,” he tells Variety. “I was shocked and surprised and felt really, really honored that they will consider me for him.”
