Al Gore is one of those people who gets me thinking about legacy. When Gore’s time on the earth comes to a close, how will he be remembered? As a solid vice president who lost one of the most hotly disputed elections of all time? Or as a champion of environmental conservationism? From the outside, it certainly appears that Gore is angling for the latter. Just this past weekend, it was announced by Paramount Pictures (via Variety) that Al Gore has been working on a sequel to his 2006 documentary An Inconvenient Truth and that the film was set to be the opening night film at next year’s Sundance Film Festival.
