2. An Inconvenient Truth
Site rank 10, IMDb rank 7; Overall Score = 17
Directed by Davis Guggenheim
This is the film that lit the fire of climate change awareness around the world. Originating from Al Gore’s speaking campaign after his unsuccessful 2000 presidential bid, the film was the first to point massive spotlights at the events caused by global warming. Despite all the evidence presented in the film, it has been dubbed “controversial” by the climate change deniers. An Inconvenient Truth won two Academy Awards in 2006.
