About the film
An Unreasonable Man is a 2006 documentary film that traces the life and career of political activist Ralph Nader, the founder of modern consumer protection in America and perennial presidential candidate. Contrary to the title's apparent message, the film was actually created to defend and support Nader, and to restore his reputation after his controversial role in the 2000 U.S. presidential election.
