Alain Bergala is a critic, filmmaker, teacher at la Femis – the French national cinema school, and artistic advisor to Cinéma, cent ans de jeunesse. Using a selection of clips from the history of cinema, taking in work by the Lumiere Brothers all the way to recent releases, he looks at how weather and climate lie at the very heart of cinema itself: How it affects the representation of reality on screen, by way of involuntary and unconscious gestures, or by way of more consciously controlled gestures and actions – the creation and application of artifice, the impressionistic treatment of sensation and emotion, weather events which form part of the core of the drama and conception of the film, or which transform the world and the image in front of our eyes.
