Nowadays, music videos done by noted auteurs are hardly a rare thing: Wong Kar-wai, David Lynch, Claire Denis, and Philippe Grandrieux have made them, among many others.
Far rarer are filmmakers who, for some reason or another, decided to dabble in the genre not just in its infancy but in their old(-ish) age as well. Did you know both Eric Rohmer and Michelangelo Antonioni directed music videos in the 1980s? Rohmer was 66 years old when he directed Bois ton café, and Antonioni was 72 (!) when he directed the video for Gianna Nannini's Fotoromanza. Do you know any other late-age auteur music videos?
