Now, a new documentary has increased curiosity around Powell’s life. It’s called American Anarchist and it’s the work of filmmaker Charlie Siskel. Siskel says he knew about the book when he was growing up. “It was notorious. It was the kind of thing that kids in the suburbs had to get their parents angry.” He says knowing about the book’s legacy got him thinking about its author — so he tracked Powell down. American Anarchist, which was filmed before Powell’s death, is a dialogue between the author and filmmaker.
