U2 have unveiled the trailer for their recent documentary From The Sky Down.
The trailer, which can be watched below on Gigwise, charts the band's journey from 1991's Achtung Baby' to the present day.
The documentary about U2 directed by Davis Guggenheim, opened this year's Toronto International Film Festival.
Guggenheim said: "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.
“The movie From The Sky Down asks the question why."
Guggenheim famously won an Oscar for the climate change documentary An Inconvenient Truth, which featured former US vice-president Al Gore.
