In The Lord of the Rings: The Fellowship of the Ring, Bilbo Baggins calls leaving the Shire “an adventure.”
Bilbo uses the word during his birthday speech, when he announces that he is leaving Hobbiton. His decision echoes the character’s earlier travels in The Hobbit, where a journey away from home transforms him from a comfort-loving hobbit into a resourceful traveler.
The speech begins as a cheerful celebration but turns mysterious when Bilbo uses the One Ring to disappear. He then leaves the Ring with Frodo, setting the central quest of the trilogy in motion. The contrast between Bilbo’s lighthearted description and the danger ahead is part of the scene’s appeal.
The phrase is sometimes remembered as “a great adventure,” but the key answer is “an adventure.” Peter Jackson’s film was released in 2001 and adapts the opening portion of J. R. R. Tolkien’s 1954 novel.
