The Hobbit (1977)

Other mistake: When Bilbo is looking at Thror's Map, he says "This hand points from these runes," but there are no runes visible where the hand is. Later, Elrond reads the Moon Letters that appear there, and says that they say, "Stand by the grey stone when the Thrush knocks, and the last light of the setting sun will shine upon the keyhole." But the Moon Letters actually translate to "Five feet high the door and three may walk abreast."

Gandalf the Grey: Surely you don't disbelieve the prophecies because you helped bring them about? You don't really suppose, do you, that all your adventures and escapes were managed by mere luck, just for your sole benefit? You're a very fine person, Mr. Baggins, and I'm very fond of you, but you're only quite a little fellow in a wide world, after all.
Bilbo Baggins: Thank goodness.
