Bill W. took eight years of full-time work to complete. The filmmakers conducted research in dozens of archives and private collections, and interviewed A.A. members and historians in the United States, Canada, and Europe.
Making a film about the founder of an anonymous society, especially one who died in 1971, presented many obstacles, of course. Very few people who knew Bill W. were still alive at the time this production began. At first, it seemed as if there would be very little visual material available for use in a film. But research and a healthy dose of good fortune allowed the producers to unearth film footage and photographs – including some that had never been seen before – and some new material that had not been included in previous written biographies of Bill Wilson. As a result, Bill W. presents a new look at the co-founder of Alcoholics Anonymous.
