An Inconvenient Truth is a 2006 American documentary film directed by Davis Guggenheim about former vice president of the United States Al Gore's campaign to educate people about global warming. The film features a slide show that, by Gore's own estimate, he has presented over 1,000 times to audiences worldwide. The idea to document Gore's 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 his slide show that she, with producer Lawrence Bender, met with Guggenheim, and Co-Producer Lesley Chilcott, to adapt the presentation into a film.
