I saw this movie in the late 1960s in an experimental film series at the University of California at Davis, organized by Neal Kreitzer. There is no plot, as I recall. We just watch a herd of horses run through a pond covered with burning oil at night--or at least that's all I remember happening. The colors are brilliant but moody, the motion is incessant, and the sound is unnerving. The film is exciting, frightening, beautiful, and all between. I can't imagine it would win many awards from the Society for the Prevention of Cruelty to Animals, but perhaps there is a disclaimer letting us know that no harm came to any of the participating animals. In any case, the images have stayed in my head for nearly 40 years, so perhaps that's worth something (for the movie, not for me).
