There is no sound in space and Cuaron honoured the scientific element by keeping all the sound effects inside the spaceship and helmets, reported Entertainment Weekly.
But instead of no-sound, he used the music store by Steven Price, which won an Oscar.
Cuaron, however, is bring a special edition Blu-Ray version of 'Gravity' where fans can experience "the film without music for a surprising cinematic experiment".
The new version will remove Price's score while retaining only the voices of Sandra Bullock and George Clooney's characters.
