In The Lord of the Rings films, appearances can be deceiving. In fact, by the time Elrond is introduced in The Lord of the Rings, he is actually well over six thousand years old.
Born in Beleriand
during the First Age, Elrond was known for being the son of Eärendil and Elwing. Elrond is also known for being the great-grandson of Lúthien, a Half-Elven character who falls in love with a mortal man called Beren. It is said that Lúthien was created by Tolkien and inspired by his own wife.
Of course, Elrond is not alone. LOTR fans have also noted a similar change from the books, where Frodo is actually older than his fellow hobbits. In the films, actor Elijah Wood was the youngest actor out of the main four hobbits (Sam, Merry, and Pippin).
