Bill W.

As the filmmakers trace the troubles of his later life -- psychological, financial, marital -- they flesh out a portrait of a reluctant guru whose human imperfections make him all the more inspiring.

Showing deep appreciation for Wilson's influence, as well as for the obscurity in which he spent his career in the spiritual-rescue business, the helmers employ a motherlode of photographs, diary entries, correspondence and recorded speeches to tell a sensational story that many will think they know, but don't.

A loving, exhaustive, warts-and-all look at the man who spent years battling his own alcoholism before a spiritual experience in the hospital set him on the course to help others.

Bill W., an admirable, illuminating film about the co-founder of Alcoholics Anonymous, is pretty much like the man himself: solid, sometimes flawed and seriously unflashy.

A key part of AA was anonymity: "Who you see here, what you say here, let it stay here." Bill Wilson himself was not anonymous - that horse was already out of the barn - and his fame was such that Time magazine named him as one of the 100 most influential men of the century. Told he should be on a postage stamp, he said: "They'd have to show the back of my head."

Names and events are ticked off in rapid succession, and the big, and fascinating, question of what role spirituality played receives cautious attention at best. Nonetheless, Bill W. offers a trove of information for non-A.A. members through the life of a man whose dedication has helped others understand their own.

Despite the filmmakers' efforts to humanize Wilson, however, Bill W. still dabbles in hagiography, valorizing the man while also painting him as a reluctant hero.
