John Turturro talks about writing, directing, and starring in “Fading Gigolo.” The film is about people’s endless and never fully satisfying quest to find happiness through sex and love, and it features Woody Allen, who plays a man who helps develop a scheme to get out of debt by entering into the world’s oldest profession. Turturro will also talk about his role in the film “God’s Pocket,” directed by John Slattery and also starring Philip Seymour Hoffman, which will be released in May.
