Director Alfonso Cuarón describes Tavener's "Fragments of a Prayer," as "a spiritual comment rather than a narrative support." The track features mezzo-soprano Sarah Connolly and is used as a powerful motif. Unlike most composers, Tavener chose not to score the piece to the film, but to the screenplay instead.[3]
The poetry of William Blake is featured in the lyrics to "Eternity's Sunrise", a work Tavener had previously written and dedicated to Princess Diana after
her death.[4]
Gustav Holst's "Mars" is used in the film although it is not on the album.
"Eternity's Sunrise" is featured Oliver Stone's movie "Savages".[citation needed]
