Though the film score is by Carter Burwell, the trailer — produced for Fox Searchlight Pictures by Aspect Ratio — features music from two production libraries: Scorebird supplied the light piano music for the opening, which segues to orchestral swells Elephant Music. “We were looking for emotional, beautiful music that had a build and could carry the story,” said Aspect Ratio music supervisor Lana Bui, noting “We spend months working on a single piece, working with the editor and the producer. And unlike music supervisors on feature films and TV shows, we’re working on 20 or 30 different projects at one time.” In addition to trailers, the company also creates television spots.

Goodbye Christopher Robin hits U.S. theaters Oct. 13. The story of Winnie The Pooh author A. A. Milne and the son whose life and toys inspired his fanciful tales is directed by Simon Curtis (My Week with Marilyn, Woman in Gold). It stars Domhnall Gleason as the author A.A. Milne and Margot Robbie as his wife, Daphne. Wil Tilston is Christopher Robin age 8, and Alex Lawther the 18-year-old Christopher. Sarah Bridge (The Theory of Everything) is the music supervisor on the film. 

Other recent work from Aspect Ratio includes trailer for New Line Cinema’s It and Netflix’s Lady Gaga documentary Gaga: Five Foot Two. and the Universal Pictures December release Pitch Perfect 3. The Santa Monica-based Scorebird Music Library specializes in original orchestral music cues.  Elephant Music & Sound Design is a sound design and library company housed within the Warner/Chappell family, with offices in Los Angeles, NY, Nashville and Salt Lake City.

Sony Classical will release Carter Burwell’s Goodbye Christopher Robin original motion picture soundtrack, which arrives digitally on Sept. 29 and on CD Oct. 20.  “Whether the onscreen action is obvious or subtle, Carter Burwell’s elegant score is understatement personified,” writes The Hollywood Reporter reviewer Sheri Linden. “It complements the point of view that defines the film — that of [Christopher Robin]. Like many astute kids, he sees his parents’ vulnerabilities and understands more than he can articulate.”
