An Inconvenient Truth is a 2006 American documentary film directed by Davis Guggenheim about former United States Vice President 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 Pale Blue Dot, a Voyager 1 photo showing Earth (circled) as a single pixel from 4 billion miles (6.4 billion kilometres) away, is featured in the film. Al Gore points out that all of human history has happened on that pixel, which is the only planet where life has been discovered.

A documentary film or documentary is a non-fictional motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries".
