One of the most influential documentary filmmakers of all time, D. A. Pennebaker revolutionized both filmmaking and the rock-n-roll world with his seminal film, "Dont Look Back" (1967), starring Bob Dylan. Using experimental film techniques, Pennebaker was instrumental in changing the way documentary films were made by using handheld cameras and lighter sound equipment in order to introduce more intimacy with the film's subjects. With "Dont Look Back," which followed Dylan on his 1965 tour of England, he broke new ground with his famed "Subterranean Homesick Blues" sequence, widely considered to rock's first music video. Pennebaker followed with the equally influential "Monterey Pop" (1968), a documentary on the famous Monterey Pop Festival in 1967, featuring Janis Joplin, Jefferson Airplane and The Who that also contained one of rock's most iconic images - that of Jimi Hendrix setting his guitar on fire. Though he faltered both creatively and financially in the 1970s and 1980s, Pennebaker returned triumphant with "The War Room" (1993), an Oscar-nominated look at Bill Clinton's successful 1992 bid for president as seen from the prospective of campaign gurus James Carville and George Stephanopoulos. With other notable documentaries, "Startup.com" (2001) and "Kings of Pastry" (2009), Pennebaker cemented his status as a pioneering documentarian who almost singlehandedly constructed a style of storytelling that influenced a generation of filmmakers.
