Imagine presents a feature-length documentary about the making of U2's seminal album Achtung Baby.

Early in 2011, U2 returned to Hansa Studio in Berlin to discuss the making of Achtung Baby in this film directed by Academy Award winner Davis Guggenheim (It Might Get Loud, Waiting for Superman, An Inconvenient Truth). From The Sky Down was then selected to open the Toronto International Film Festival on 8 September, the first ever documentary to open the festival in its 36-year history.

Twenty years after the 1991 release of Achtung Baby, Davis Guggenheim traces the album's genesis using animation and previously unseen footage from Berlin and Dublin alongside interviews with the band as they reflect on what was a key chapter in their career.

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