I am adding some french movie trailers before a presentation about france for a class. I was looking to make the experience a little more authentic. They will be vintage old b&w trailers. What do they play before movies in france? Sometimes in America they will play little cartoons, to get people to buy snacks. Or sometimes commercials. Something like this: http://www.youtube.com/watch?v=FHH3ot8fkgg But for french theaters. Any help is appreciated.
