The 20th anniversary of "Achtung Baby" was marked by several releases in 2011. At the band's request, a documentary film about the album entitled "From the Sky Down" was produced. It was directed by Davis Guggenheim, who previously collaborated with the Edge for the documentary "It Might Get Loud" in 2008. "From the Sky Down" documents the album's difficult recording period, the band members' relationships, and U2's creative process. Archival footage and stills from the recording sessions appear in the film, along with unreleased scenes from "Rattle and Hum". For the documentary, the band were filmed during a return visit to Hansa Studios and during rehearsals for the Glastonbury Festival 2011. The film premiered at the 2011 Toronto International Film Festival, becoming the first documentary to open the festival, and in October, it was broadcast on multiple television networks worldwide.
