The 36th annual Toronto International Film Festival (TIFF) was held in Toronto, Ontario, Canada between September 8 and September 18, 2011. Buenos Aires, Argentina was selected to be showcased for the 2011 City to City programme. The opening film was From the Sky Down, a documentary film about the band U2, directed by Davis Guggenheim. Considerable media attention at the time focused on Madonna's behaviour during the festival.

From the Sky Down is a 2011 American documentary film directed by Davis Guggenheim about rock band U2 and the production of their 1991 album Achtung Baby. The film documents the album's difficult recording period, the band members' relationships, and the group's creative process. Guggenheim, who was commissioned by U2 to create the film to commemorate the record's 20th anniversary, spent several months in 2011 developing the documentary. The band were filmed during a return visit to Hansa Studios in Berlin where parts of the album were recorded, and during rehearsals in Winnipeg for the Glastonbury Festival 2011. The film contains unreleased scenes from the group's 1988 motion picture Rattle and Hum, along with archival footage and stills from the Achtung Baby recording sessions. Development of the album's emblematic song "One" is recounted through the replaying of old recording tapes.
