The Lord of the Rings movies do a great job adapting J.R.R. Tolkien's epic fantasy story, but that doesn't mean they include all the details from the books. The director of the original films, Peter Jackson, has to omit some aspects of the narrative to keep the pace moving quickly and ensure that the most important parts of the plot take center stage. However, one of the best parts of Tolkien's work is how immense and comprehensive the lore is. Every race in Middle-earth has a rich history, and all the characters' actions have deeper motivations that we never see in the movies.
