Woody Allen's new film, Midnight in Paris, is a romantic comedy starring Owen Wilson. He plays Gil Pender, a Hollywood screenwriter, on a trip to Paris with his fiancee. He yearns for what he considers the city's golden age, Paris of the 1920s, when American writers like Ernest Hemingway and F. Scott Fitzgerald lived there. One night while wandering the streets, Gil is transported back in time and finds himself face to face with those literary giants. Robert Siegel talks with actor Corey Stoll about playing Hemingway on the screen.
