Cinema, the art of illusion par excellence, is still mainly a man's job. Among the women who have succeeded in making a name for themselves at international level is a French woman: Anne Seibel. She is one of the most respected designers in the industry, both in Europe and the United States. She has worked with the greatest, from Clint Eastwood to Woody Allen, Spielberg and Benegal. Where does she draw her inspiration from and how does she manage to renew it, as she adapts to such different worlds?
