Bilbo tells the dwarves to "run back to the wood-elf clearing" while he fights a rearguard action against the Mirkwood spiders. However, the company has not yet met the wood-elves. When they reach the clearing, Bilbo notes that the wood-elves "had returned, armed for battle". This is the first time we see the wood-elves. There is a scene from the book which was clearly scripted but is missing from the animation, where the starving dwarves attempt to gate-crash a gathering of wood-elves in a clearing.
When Elrond reveals the moon runes on the dwarves' map, he reads the phrased as quoted directly from the book "Stand by the grey stone...", however the phrase shown is "Five feet high the door and three may walk abreast." This is a phrase which was not written in the moon runes.
