For Martin Scorsese to have directed this loving biopic about author Fran Lebowitz's life, one assumes that not only must she have enormous talent, but that she, as a character, can also entertain viewers enough to warrant the making of a feature-length documentary. Indeed, as Lebowitz says in one interview among the many here, she is first and foremost a public speaker, a woman who takes talking to a high art form after she dreamed, as a child, that people would care about her opinions. Public Speaking chronicles a truly iconoclastic author and thinker whose satirically barbed wit is hilarious and controversial on the page, as well as onscreen. In her interviews she pontificates most vocally about her experiences as a New Yorker, as a writer, journalist, feminist, smoker (yes, she actually takes the protection of cigarette smoking rights up as a cause), and gay rights activist. What it adds up to, in her words, is a devotion to maintaining individual freedom. Most poignant, however, are the scenes in which she places herself historically within a New York cultural framework, as she remembers first writing for Andy Warhol's Interview magazine, then publishing her first hit novel, Metropolitan Life. Of course, while tracking any influential author's career is important, Scorsese does a wonderful job of taking a wider cultural stance, occasionally editing in footage of James Baldwin, Truman Capote, Gore Vidal, and other radical authors to trace an American history of literary satire's ties to political causes. Lebowitz, who has been called a modern-day Dorothy Parker, astutely expresses brilliant, miniature rants on topics ranging from how wit could be connected to religious and cultural roots, to the equal importance of smart cultural audiences and artists.
