A secret collaboration hidden behind clouds and decoy trailers
In short: When Taylor Swift was asked to write for Toy Story 5, she initially declined. It took a personal letter from a producer—arguing that her experience in a male-dominated industry made her the perfect voice—to change her mind. The result was a record-breaking country-pop ballad born in just eight hours.
In September 2025, Disney and Pixar producer Jessica Choi reached out to Taylor Swift with a specific pitch: the studio wanted a female-focused approach for Toy Story 5. Choi argued that Swift’s career navigating a male-dominated industry provided a unique perspective that was necessary for the film's narrative. Swift eventually agreed to an early screening in February 2026, after which she and collaborator Jack Antonoff wrote and produced 'I Knew It, I Knew You' in a single eight-hour session.
The song is written from the perspective of Jessie, exploring themes of reunion and memory. Critics noted its narrative depth, with Swift using country-style songwriting to describe an unexpected meeting between loved ones who were thought lost. The track features 14 instruments—including banjo, mandolin, and celesta—and was designed to mirror the musical sensibilities of Randy Newman, the franchise's longtime composer. It became a historic milestone for both studios, marking Disney’s first number-one debut on the Billboard Hot 100 and Pixar’s first chart-topper.
To maintain secrecy, Pixar created a 'decoy version' of the film without the song for press and unaware crew members; even the voice cast remained in the dark until hours before the announcement. The marketing campaign was a masterclass in subtle signaling: Swift’s 1989 (Taylor's Version) cover art was altered to replace seagulls with clouds, and her 'essentials' playlist on Apple Music was updated so that every 'T' and 'S' in the lyrics were capitalized.
