You may be interested in this recent review of Antero Alli’s To Dream of Falling Upwards:
“His newest film is set among adherents of an occult Order, somewhat resembling the Magickal cults which practice Thelema, a discipline inspired by the work of Aleister Crowley. The complex, expertly constructed story involves a struggle for succession of the Order, a murder, and a demonic possession. The twists of the story kept me glued to the screen through several viewings, mainly because of the way they gradually reveal new layers of the inner lives of the characters.”
