TORONTO (AP) — U2 singer Bono, guitarist The Edge and their band mates have let their guard down for a revealing documentary about their creative development and a pivotal career shift 20 years ago.

"From the Sky Down" opened the Toronto International Film Festival on Thursday night, the first time in its 36-year history that the prestigious cinema showcase began with a documentary. The film centers on the band's renewed sense of purpose on the 1991 album "Achtung Baby."

The Edge and Bono joined director Davis Guggenheim for two screenings of the film. Bono told the crowd before the first screening that the band is protective of its privacy and creative process, joking that if people "knew what went into the sausage, you wouldn't eat the sausage."
