One of the standout aspects of "The Hobbit" movies was the return of key actors from "The Lord of the Rings," including Hugo Weaving as Elrond. Weaving was thrilled to reprise his role, even joking that he looked younger than he did in the original trilogy. He enjoyed reconnecting with old cast members and having fun on set. There’s also speculation that he could return as Elrond in future projects, like a rumored Gollum movie.
