With regard to film projection, we have an excellent film entitled HOW YOU SEE IT, produced by Jam Handy Organization for Chevrolet in 1937. Although it's a soft-sell ad for Chevrolets (Chevies appear throughout the film in unpredictable places) the film explains persistence of vision and the workings of the projector in an amusing and well-thought manner. It also offers food for thought for those who may be concerned with the phenomenology of movie projection, the construction of spectatorship, and the centrality of the car in American culture. All this, in a mere 7 minutes. I'd be pleased to send you a tape if the Cinematheque wants to consider using it in the show. Rick Prelinger Prelinger Archives, New York [log in to unmask]
