Antonio Sanchez’s score for the film ”Birdman” has been disqualified for Oscar consideration by the Academy of Motion Picture Arts & Sciences.

Though Sanchez appealed the decision, submitting a detailed cue sheet and a description of the how the music came to be from “Birdman” director Alejandro González Iñárritu, the original judgment was upheld, according to a report in Variety.

A drummer and composer, Sanchez is best known for his work with Pat Metheny, and has recorded with Michael Brecker, Gary Burton, Chick Corea and other jazz artists. His score for “Birdman” relies heavily on his improvisational drumming, and its skittish, careening, propulsive nature seemed ideal for the film.

Sanchez believes the disqualification stems from the use of several classical themes in the film. Academy rules state that “scores diluted by the use of tracked themes or other pre-existing music, diminished in impact by the predominant use of songs, or assembled from the music of more than one composer shall not be eligible.”

But this rule hasn’t been applied consistently. Gustavo Santaolalla's Oscar-winning score for "Babel" contained at least three prominent pieces that appeared in earlier films and on albums – Santaolalla's "Iguazu," which was in "The Insider," Michael Mann's 1999 film, and on Santaolalla's 1998 album "Ronroco"; and two compositions by Ryuichi Sakamoto that appeared on his albums.

Sanchez’s score for “Birdman” has been nominated for Critics’ Choice and Golden Globe awards.
