I was very pleased to hear that the work of G. Melies, the inspiration for The Invention of Hugo Cabret is now released on DVD. I was thinking about this and mused that surealism, dream-like realities, and more primary (native?) to film then the realism of Passolini, or the modern usage of film. Where somehow the realism seems to have less in common with a human reality. Reality v. appearance.
And then I was thinking about all the ways in which technology changes art--the camera making realism in painting obsolete, and paint in tubes making expressionism possible. One could easily paint outside. And use a lot of paint.
