Pizzazz! Divine! The 2012 movie "Diana Vreeland: The Eye Has to Travel," which just came out on DVD a few days ago, has really taken me back into the milieu inhabited by Richard Avedon during the years that I assisted him, 1952-1965. To watch this documentary, made from period clips, is to understand a great deal more about the world he moved in. There are interviews with him, and clips from the 1957 feature film "Funny Face," loosely based on his life — in which the imaginary role of Avedon was played by Fred Astaire and that of Diana Vreeland by Kay Thompson.
