Liv Tyler played Arwen Undómiel in Peter Jackson's film trilogy "The Lord of the Rings."
Arwen is an Elf of Rivendell and the daughter of Elrond, the half-Elven lord played by Hugo Weaving. She is the beloved of Aragorn, and their relationship becomes central to the trilogy's themes of love, duty and mortality. Arwen ultimately chooses a mortal life with Aragorn rather than sailing into the Undying Lands.
Tyler portrays Arwen across all three films: "The Fellowship of the Ring" (2001), "The Two Towers" (2002) and "The Return of the King" (2003). The movies expand her role compared with Tolkien's books, giving her more visible involvement in the story and emphasizing her courage during the journey.
A frequent mix-up is identifying Tyler with Éowyn, another important woman in the trilogy. Éowyn is a human warrior of Rohan, played by Miranda Otto. Arwen is the Elven character associated with Rivendell and Aragorn's romance.
