A Sacred Duty, subtitled "Applying Jewish values to help heal the world," is a 2007 60-minute documentary from Jewish Vegetarians of North America (JVNA), written and produced by Lionel Friedberg.
 The film focuses on Jewish teachings about caring for the earth, treatment of animals, and the environment, with a focus on vegetarianism.
 Interviews with rabbis, activists, and scholars are interspersed with footage and stills illustrating the points being discussed.
Inauguration of the Pleasure Dome is a 38-minute short film by Kenneth Anger, filmed in 1954.
 Anger created two other versions of this film in 1966 and the late 1970s.
 According to Anger, the film takes the name "pleasure dome" from Samuel Taylor Coleridge's atmospheric poem "Kubla Khan".
 Anger was inspired to make the film after attending a Halloween party called "Come as your Madness".
 The film has gained cult film status.
Eaux d'artifice (1953) is a short experimental film by Kenneth Anger.
 The film was shot in the Villa d'Este in Tivoli, Italy.
 The film consists entirely of a woman dressed in eighteenth-century clothes who wanders amidst the garden fountains of the Villa d'Este ("a Hide and Seek in a night-time labyrinth") to the sounds of Vivaldi's "Four Seasons", until she steps into a fountain and momentarily disappears.
 The actress, Carmilla Salvatorelli (not "Carmello"), was "a little midget" Anger had met through Federico Fellini.
 Anger used a short actress to suggest a different sense of scale, whereby the monuments seemed bigger (a technique he said was inspired by etchings of the gardens in the Villa d'Este by Giovanni Battista Piranesi).
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.
 He has also focused upon occult themes in many of his films, being fascinated by the English poet and mystic Aleister Crowley, and is an adherent of Thelema, the religion Crowley founded.
New Folk Media is a developing movement in experimental film and video art which is concerned with the use of existing media for artistic expression without regard for copyright or ownership.
 The movement traces its roots in Joseph Cornell and his film Rose Hobart and other found footage films.
 It can also be traced to Sergei Eisenstein's aborted film project Que Viva Mexico which has been edited by countless filmmakers and artists including Kenneth Anger.
 Other early examples that have influenced the development of New Folk Media can be found in the works of Bruce Conner, Jonas Mekas, Ken Jacobs, Craig Baldwin and Kenneth Anger.
Scorpio Rising is a 1963 American experimental short film by Kenneth Anger, starring Bruce Byron (whom Anger asserts was "half-crazy") as Scorpio.
 Themes central to the film include the occult, biker subculture, homosexuality, Catholicism, and Nazism; the film also explores the worship of rebel icons of the era, such as James Dean and Marlon Brando (referred to by Anger as Byron's "heroes").
 Like many of Anger's films, the film does not contain any dialogue; it instead features a prominent soundtrack consisting of 1960s pop, including songs by Ricky Nelson, The Angels, The Crystals, Bobby Vinton, Elvis Presley, and Ray Charles.
Lionel Friedberg is a documentary film director, producer and writer who has written or produced films for Animal Planet, CBS, PBS, the History Channel, the Discovery Channel and National Geographic Channel.
 He has 18 credits as Director of Photography on feature motion pictures, and has worked all over the world on both dramatic and nonfiction productions.
George Albert "Scotty" Bowers (born July 1, 1923) is a former Marine who, from the 1940s to the 1980s, was a Hollywood pimp.
 Stories of his exploits circulated for many years, and were alluded to in books such as Hollywood Babylon.
 Bowers finally decided to talk publicly about his life when most of the people involved were dead and could no longer be affected by his revelations.
 In 2012 the publication of his memoir "Full Service", written by Lionel Friedberg from 150 hours of interviews, drew publicity, including a profile in the" New York Times", and a feature on "CBS News Sunday Morning".
 One journalist has written, "He has a savant-like quality: a result of his refusal to be embarrassed by sex."
Richard H. Schwartz (born April 10, 1934) is a professor emeritus of mathematics at the College of Staten Island; President of the Jewish Vegetarians of North America (JVNA); and co-founder and coordinator of the Society of Ethical and Religious Vegetarians (SERV).
 He is best known as a Jewish vegetarian activist and advocate for animal rights in the United States and Israel.
 His writings inspired the 2007 documentary film, "A Sacred Duty: Applying Jewish Values to Heal the World", directed by Lionel Friedberg.
 Schwartz and JVNA have arranged to give away about 40,000 complimentary DVDs of the video and have arranged to have it seen freely at aSacredDuty.com.
Full Service: My Adventures in Hollywood and the Secret Sex Lives of the Stars is a "tell all" book about the sex lives of Hollywood stars from the late 1940s to the early 1980s by Scotty Bowers, with Lionel Friedberg as a contributing author.
 Bowers makes many claims about the sex lives of many people, most of whom were associated with the Hollywood movie industry during that period.
 The book, which was vetted by a libel lawyer before publication, was refused by several publishers before ultimately being accepted by Grove Press and Grove/Atlantic.
 Matt Tyrnauer, director of "", is currently in production on a documentary film about Bowers's life.
