Who composed the music for Avatar: Fire and Ash?

Simon Franglen composed the music for Avatar: Fire and Ash. Franglen served as the film's composer and continued the musical identity of the Avatar series, combining new material with themes and musical ideas associated with Pandora, Jake Sully, and the Na'vi.

Franglen had already been closely involved with the franchise before composing Fire and Ash. He worked with James Horner on the original Avatar (2009), contributing to the film's music production, and later composed the score for Avatar: The Way of Water (2022). His return helped maintain continuity across the series while allowing the third film to develop its own musical atmosphere.

James Horner is a common source of confusion because he composed the score for the first Avatar and created the franchise's original musical foundation. Michael Giacchino composed the music for other major film franchises, while Hans Zimmer has scored numerous large-scale action and science-fiction films. For Fire and Ash specifically, the credited composer is Simon Franglen.
