An Inconvenient Truth is a 2006 documentary film directed by Davis Guggenheim about former United States Vice President Al Gore's campaign to educate citizens about global warming via a comprehensive slide show that, by his own estimate made in the film, he has given more than a thousand times.
Premiering at the 2006 Sundance Film Festival and opening in New York City and Los Angeles on May 24, 2006, the documentary was a critical and box-office success, winning two Academy Awards for Best Documentary Feature and Best Original Song. The film grossed $24 million in the U.S. and $26 million in the foreign box office, becoming the tenth highest grossing documentary film to date in the United States.
The idea to document his efforts came from producer Laurie David who saw his presentation at a town-hall meeting on global warming which coincided with the opening of The Day After Tomorrow. Laurie David was so inspired by Gore's slide show that she, with producer Lawrence Bender, met with Guggenheim to adapt the presentation into a film.
Since the film's release, An Inconvenient Truth has been credited for raising international public awareness of global warming and reenergizing the environmental movement. The documentary has also been included in science curricula in schools around the world, which has spurred some controversy. An Inconvenient Sequel: Truth to Power will be in theaters July 28, 2017.
