Hollis Frampton "Zorns Lemma" (1970)

The best poetry film ever made.

This is an amazing experimental film from American avant-garde filmmaker Hollis Frampton. It begins with a dark screen and a woman narrating from The Bay State Primer, an early American grammar textbook that teaches the letters of the alphabet by using them in sentences derived from the Bible, then the rest of the film is mostly silent. It presents us with a recurring structure that perpetually moves throughout a 24-letter alphabet via various signs in New York with words that propel the film along. Gradually other images are added to the loop, some of them themselves slowly developing as we arrive at them the next time around. It concludes with a man, woman and dog crossing a snowy field, while several narrators each narrate one word at a time read from an 11th century treatise, "On Light, or the Ingression of Forms", by Robert Grosseteste. Ambiguous, metaphorical and fascinating. A veritable masterpiece of structural filmmaking.
