Twenty years after the release of 'Achtung Baby', director Davis Guggenheim's documentary 'From The Sky Down' will open the Toronto International Film Festival in September.

Guggenheim (Waiting for Superman, An Inconvenient Truth, It Might Get Loud) charts this groundbreaking album with new interviews, stories and unseen footage from Berlin and Dublin.

Now a key chapter in their career, Achtung Baby was, in Bono’s words, 'the sound of four men chopping down The Joshua Tree'.

'In the terrain of rock bands, implosion or explosion is seemingly inevitable, ' explains Guggenheim. 'U2 has defied the gravitational pull towards destruction, this band has endured and thrived. The movie From The Sky Down asks the question why.'

The Toronto International Film Festival® opens September 8 with the world premiere Gala Presentation of From the Sky Down, the first time in 36 years that the Festival has opened with a documentary.
