The Lord of the Rings (movie series)
Compared to the book, the Lord of the Rings movies differed in many ways. The plot and motivation of the characters changed, and parts of the story were cut. A few changes that many consider major include: "The Old Forest", "In the House of Tom Bombadil", and "Fog on the Barrow-Downs", from The Fellowship of the Ring; "Many Partings", "Homeward Bound", & "The Scouring of the Shire" from The Return of the King. These were left out, and other passages changed, because of dramatic flow and practical limits on what could be presented in three movies. The scripts are not exactly true to the story in the volumes of the book, yet have most of its most important elements.
