Those who claim Hollywood is an ant’s nest of Democratic and liberal activism are already riled up over Saturday’s debut of HBO’s Sarah Palin pic Game ChangeNow they will have more reason to shake a fist at the entertainment community with today’s unveiling of the 2-minute trailer for The Road We’ve Traveled, a new campaign video for President Obama’s re-election effort. Narrated by Oscar-winner Tom Hanks at his most passionate and directed by Davis Guggenheim (director of Al Gore’s Oscar-winning documentary An Inconvenient Truth), the 17-minute film will be released March 17. The trailer, which debuted this morning on social media sites like Facebook, features comments from Vice President Joe Biden, former Chief of Staff (and current mayor of Chicago) Rahm Emanuel, former economic advisor Austan Goolsbee and others. Republicans are already foaming at the mouth over the trailer, while the Obama faithful are waiting anxiously for the remaining 15 minutes. Such is life in the 2012 election season.
