Kenneth Anger (born February 3, 1927) is a Californian underground avant-garde film-maker and author.
Anger's lifelong interest in the occult, particularly in the works of Aleister Crowley, brought him into contact with a variety of groups and individuals. He was a lifelong friend of Anton LaVey, both before and after the founding of the Church of Satan in the 1960s, and lived with LaVey and his family during the 1980s. In more recent years Anger has accepted initiation into Ordo Templi Orientis.
