D.A. Pennebaker ("Opiate Addiction: A New Medication," "Opiate Addiction: Understanding Replacement Therapy") made his filmmaking debut with the 1953 short "Daybreak Express." In 1959 Pennebaker joined Drew Associates, a group of filmmakers dedicated to furthering the use of film in journalism. This helped Pennebaker and his colleagues establish what became known as "cinema verite." Together, they produced such landmark films as "Primary," "Crisis" and "Jane." Since 1977 Pennebaker has partnered with Chris Hegedus on a host of acclaimed films. Most recently they codirected, with Nick Doob, "Elaine Stritch at Liberty," which earned three Primetime Emmy® nominations, including Outstanding Direction of a Music, Comedy, or Variety Program. In 2003 they completed "Only the Strong Survive" about some of the legendary r'n'b performers. The team received the D.W. Griffith Award for Best Documentary of the Year and an Academy Award® nomination for their 1994 film "The War Room," which followed Bill Clinton's first presidential campaign.
