[2] For the film's soundtrack, director Peter Farrelly incorporated an original score by composer Kris Bowers and one of Don Shirley's own recordings.

This rate doubled the next month as the album surpassed one million streams worldwide and became the highest-streamed jazz soundtrack in Milan's history.

During dinner on a double date, his wife and her friend stepped outside to smoke and the director asked Plant for advice on picking songs for the film that would be relatively unknown to contemporary audiences.

Don Vito, the film's editor had color corrected Bower's hands to match Ali's skin tone, and also edited his other body parts, to replicate the tune.

[11] Critical reviews for the score were positive, with Ani Bundel of Elite Daily felt that "The soundtrack is a celebration of this music, even including a piano piece played by the real Don Shirley, plus many other fantastic songs of the era, intermixed with original compositions by the movie's composer, Kristopher Bowers".

[3] The Film Scorer wrote "Although his score for Green Book may not necessarily be remembered in the years to come, Bowers’ work in reproducing Shirley’s original music will be, both for its skill and its reintroduction of a classical and jazz great to a new audience.
