<human>: Kenneth Anger (born Kenneth Wilbur Anglemyer; February 3, 1927) is an American underground experimental filmmaker, actor and author. Working exclusively in short films, he has produced almost forty works since 1937, nine of which have been grouped together as the "Magick Lantern Cycle". His films variously merge surrealism with homoeroticism and the occult, and have been described as containing "elements of erotica, documentary, psychodrama, and spectacle". Anger himself has been described as "one of America's first openly gay filmmakers, and certainly the first whose work addressed homosexuality in an undisguised, self-implicating manner", and his "role in rendering gay culture visible within American cinema, commercial or otherwise, is impossible to overestimate", with several being released prior to the legalization of homosexuality in the United States.

As Anger discovered his homosexuality, at a time when homosexual acts were still illegal in the United States, he began associating with the underground gay scene. At some point in the mid-1940s, he was arrested by the police in a "homosexual entrapment", after which he decided to move out of his parents' home, gaining his own sparse apartment largely financed by his grandmother, and abandoning the name Anglemyer in favor of Anger. He started attending the University of Southern California, where he studied cinema, and also began experimenting with the use of mind-altering drugs like cannabis and peyote. It was then that he decided to produce a film that would deal with his sexuality, just as other gay avant-garde film makers like Willard Maas were doing in that decade. The result was the short film Fireworks, which was created in 1947 but only exhibited publicly in 1948.  Upon release of the work, Anger was arrested on obscenity charges. He was acquitted, after the case went to the Supreme Court of California, which deemed it to be art rather than pornography. Anger made the claim to have been seventeen years old when he made it, despite the fact that he was actually twenty, presumably to present himself as more of an enfant terrible. A homoerotic work lasting only 14 minutes, Fireworks revolves around a young man (played by Anger himself) associating with various navy sailors, who eventually turn on him, stripping him naked and beating him to death, ripping open his chest to find a compass inside. Several fireworks then explode, accompanied by a burning Christmas tree and the final shot shows the young man lying in bed next to another topless man. Of this film, Anger would later state in 1966 that "This flick is all I have to say about being 17, the United States Navy, American Christmas and the fourth of July." He would continuously alter and adapt the film up until 1980, with it finally being distributed on VHS in 1986.  One of the first people to buy a copy of Fireworks was the sexologist Dr. Alfred Kinsey of the Institute for Sex Research. He and Anger struck up a friendship that would last until the doctor's death, during which time Anger aided Kinsey in his research. According to Anger's unofficial biographer Bill Landis, Kinsey became a "father figure" whom Anger "could both interact with and emulate." Meanwhile, in 1949 Anger began work on a film called Puce Women, which unlike Fireworks was filmed in color. It starred Yvonne Marquis as a glamorous woman going about her daily life; Anger would later state that "Puce Women was my love affair with Hollywood... with all the great goddesses of the silent screen. They were to be filmed in their homes; I was, in effect, filming ghosts." A lack of funding meant that only one scene was ever produced, which was eventually released under the title Puce Moment. That same year, Anger directed The Love That Whirls, a film based upon Aztec human sacrifice but, because of the nudity that it contained, it was destroyed by technicians at the film lab, who deemed it to be obscene.
