Which composer wrote the music for the 2010 film 'Inception'?

Hans Zimmer wrote the music for the 2010 film Inception.

Zimmer’s score helped define the film’s dreamlike, tense atmosphere with dense electronic textures, deep brass sounds, and slow-building musical layers. Inception was his third collaboration with director Christopher Nolan, following Batman Begins and The Dark Knight. Zimmer worked on the music while the film was still being shot, allowing the score to develop alongside Nolan’s elaborate dream-within-a-dream structure.

One of the film’s most recognisable musical ideas grew from Édith Piaf’s song “Non, je ne regrette rien,” which appears in the story as a timing signal for the dream levels. Zimmer incorporated a slowed and transformed version of the song’s musical character into parts of the score. Guitarist Johnny Marr also contributed distinctive 12-string guitar performances.

The soundtrack was released in 2010 and earned an Academy Award nomination for Best Original Score, though Zimmer did not win that year. A common mix-up is attributing the film’s music to Nolan’s other frequent collaborator, James Newton Howard; Zimmer composed Inception’s score.
