Decades before we had reality television, there was the Loud family. From HBO Films comes the story of the groundbreaking PBS documentary 'An American Family' which chronicled the lives of the Loud family in the early 1970s. The cameras put the Louds in the national spotlight as parents Pat and Bill (Diane Lane, Tim Robbins) grappled with their marriage while raising their children. Filmmaker Craig Gilbert (James Gandolfini) felt the family's struggles were relatable to many Americans, but none of them could have predicted that the series would catapult them to notoriety and give birth to reality TV.
