Na página Wikipedia sobre Aragão:
Aragorn was voiced by John Hurt in Ralph Bakshi's 1978 animated film version of The Lord of the Rings. Bakshi's Aragorn, unlike all other portrayals that were to follow to date, has no beard. This actually conforms to a statement appearing in Unfinished Tales that implicitly says that Aragorn was not supposed to have one, due to his Elvish ancestry (Elves did not grow beards). However, Tolkien actually wrote elsewhere that Elves did have beards; in The Lord of the Rings itself Círdan is described as having a beard.
