"Inconvenient Truth" Director Had Hand in Obama Infomercial

Sen Barack Obama's half-hour infomercial, which drew rave reviews for production, was produced by two leaders of the campaign's ad team -- Jim Margolis of ad agency GMMB and Mark Putnam of ad agency Murphy/Putnam -- but it had some Hollywood help. Playing a role in its production was Davis Guggenheim, the Academy Award-winning director and executive producer of Al Gore's "The Inconvenient Truth." Guggenheim was a producer and director of HBO's "Deadwood" and has directed episodes of a number of TV shows.
