The films of Maya Deren often contain a number of aspects of 'dance' within them - in the editing style, in the camera movements, as well as actual depictions of human dance and ritualized movement. Her films are few, and generally short (often under 15 minutes apiece), as they were made on the smallest of budgets, but are held in high esteem by those who study filmmaking. Her first film, Meshes of the Afternoon, created with then-husband Alexander Hammid, a Hollywood cameraman, continues to be her most well-known work, followed by At Land, her second film. I recommend checking those out on YouTube. Below I'm including links to her most obviously dance-oriented works.
From the Wikipedia bio:
"Maya Deren (April 29, 1917 – October 13, 1961), born Eleanora Derenkowskaia (Russian: Элеоно́ра Деренко́вская), was one of the most important American experimental filmmakers and entrepreneurial promoters of the avant-garde in the 1940s and 1950s. Deren was also a choreographer, dancer, film theorist, poet, lecturer, writer and photographer."
"In 1943, she moved to a bungalow on Kings Road in Hollywood and adopted the name Maya. Maya is the name of the mother of the historical Buddha as well as the dharmic concept of the illusory nature of reality. In Greek myth, Maia is the mother of Hermes and a goddess of mountains and fields. Also in 1943, Deren began making a film with Marcel Duchamp, The Witches' Cradle, which was never completed.
In 1944, back in New York City, her social circle included Duchamp, André Breton, John Cage, and Anaïs Nin."
