[3] The film chronicles a performance of the show at the Altice Arena in Lisbon, Portugal, directed by Icelandic filmmaker Ísold Uggadóttir, with Björk billed as "sound and visual director".

The movie overlays the performances with the visuals that were projected on the screens on the background of the live setting, which were created by German artist Tobias Gremmler and several others, including Andrew Thomas Huang, Gabríela Friðriksdóttir, Warren Du Preez and Nick Thornton Jones.

[9] The shows featured the 7-piece Icelandic flute ensemble Viibra, American harpist Katie Buckley, a percussion section played by Austrian musician Manu Delago, with electronics and musical direction by Bergur Þórisson.

The creative team for Cornucopia also included choreography by Margrét Bjarnadóttir, lighting design by Bruno Poet, dresses and costumes by Iris Van Herpen and Olivier Rousteing, sound design by Gareth Fry, sound engineering by John Gale, with frequent collaborator and artist James Merry involved in the making of masks and in the visual co-direction of the show.

[12][13] The live set of Cornucopia included 27 moving curtains that captured projections on different textures and LED screens, and several bespoke instruments such as a magnetic harp, an aluphone, a circular flute, and a reverb chamber designed by Arup Group to feature a "personal chapel" on stage.

While Utopia focused on airy, light themes, Fossora was rooted in more grounded, earthy sounds, influenced by her personal life and the pandemic's impact.

[4] In a November 2023 interview with Rolling Stone, Björk confirmed that Cornucopia would be adapted into a concert film, originally slated for release in 2024.

[5] The full-length movie was previewed exclusively for Björk and collaborators at the Smárabíó cinema in Reykjavík on January 22, before being theatrically released in Iceland from February 1, 2025.
