Answer
Yes, Jack Parsons edited the 1954 documentary film Hell Bent for Hell. The film was about the life and death of Aleister Crowley, a British occultist and ceremonial magician. Parsons was friends with Crowley and was influenced by his work. He was also involved in the occult and ceremonial magic himself. The film was not a commercial success, but it is still considered an important work of occult cinema.
