take you back in this first talk about the art of film erm to the very early days, and these are difficult I think for us to imagine because we're so used today to sound films, of all the effects in, in the theatres, we're used to the great stars, we're used to the big subjects, and yet the film began in the smallest possible way, it began really as a sideshow, it began as a hobby for a group of people, sometimes they would be French, sometimes they would be British, sometimes American, the early pioneers, whose main interest was to produce a camera, which would look like a still camera and yet somehow would manage to produce a picture which moved when it was projected on a screen.
