The Wonder Ring (1955)

An important early film by Stan Brakhage, which Joseph Cornell commissioned as a record of New York's Third Avenue elevated train before it was torn down. Curiously lacking in people, the film focuses on the rhythms of the ride and reflections in train windows, finding a real-world version of the superimpositions Brakhage would later create in the lab. Preserved by the Academy Film Archive in 2005.

Unfortunately the movie The Wonder Ring is not yet available on HBO Max.
