“Haxan” was originally a Swedish-Danish silent film written and directed by Benjamin Christensen in 1922 but was later re-released in an abbreviated form in 1968 as “Witchcraft Through the Ages” with a soundtrack including Jean-Luc Ponty and Daniel Humair and narration by William S. Burroughs. Though the film was a documentary about how superstition and misunderstanding of mental illness led to the hysteria of the witch-hunts, recreations of occult rituals and torture made it banned in the US upon initial release.
