Commentators have compared Peter Jackson's 2001–2003 The Lord of the Rings film trilogy with the book on which it was based, J. R. R. Tolkien's 1954–1955 The Lord of the Rings, remarking that while both have been extremely successful commercially, the film version does not necessarily capture the intended meaning of the book. They have admired Jackson's ability to film the long and complex work at all; the beauty of the cinematography, sets, and costumes; the quality of the music; and the epic scale of his version of Tolkien's story. They have, however, found the characters and the story greatly weakened by Jackson's emphasis on action and violence at the expense of psychological depth; the loss of Tolkien's emphasis on free will and individual responsibility; and the replacement of Frodo's inner journey by an American monomyth with Aragorn as the hero.

The music of The Lord of the Rings film series was composed, orchestrated, conducted and produced by Howard Shore between 2000 and 2004 to support Peter Jackson's film trilogy based on J. R. R. Tolkien's fantasy novel of the same name. It is notable in terms of length of the score, the size of the staged forces, the unusual instrumentation, the featured soloists, the multitude of musical styles and the number of recurring musical themes used.
