Furthermore, the tracks "Map of the Problematique" by Muse, "Gimme Shelter" by The Rolling Stones, and "Hoppípolla" by Sigur Rós were used in TV spots and trailers but were not featured in the film.

Pulp frontman Jarvis Cocker's song "Running the World" is played in the credits of the film.

The film score, Fragments of a Prayer, was composed by John Tavener and released on Varèse Sarabande.

Director Alfonso Cuarón describes Tavener's "Fragments of a Prayer," as "a spiritual comment rather than a narrative support."

[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.
