Brothers Jim Mitchell (1943–2007) and Art Mitchell (1945–1991) emerged as influential figures in the adult film and entertainment industry, shaping it from the late 1960s through the early 1990s. With films such as the widely known “Behind the Green Door” (1972), they became prominent figures in the adult film industry during the Golden Age of Pornography (1969–1984) period, when feature-length pornographic films entered mainstream American culture. In addition to their film work, Jim and Art Mitchell operated the O’Farrell Theatre in San Francisco, a venue known for adult entertainment and live performances. Hunter S. Thompson, American journalist and author, and a club regular and friend of the brothers, referred to O’Farrell Theater as the “Carnegie Hall of public sex in America”. Their business activities brought them into frequent conflict with local and federal authorities, resulting in numerous arrests and legal challenges throughout the 1970s and 1980s. The dancers and models who worked at the O’Farrell navigated the venue’s long-standing reputation for grit and volatility. Nearly two-thirds of the women performing there were queer, and they built strong networks of solidarity that exposed the deeply unstable, sexualized, and sexist nature of the workplace. A significant number of the dancers were sannyasins, followers of the Indian mystic Bhagwan Shree Rajneesh, connected to the Rajneeshpuram commune near Antelope, Oregon. Believing that suppressing sexuality was a form of oppression, these followers were at ease with sex work and helped spread the word that the O’Farrell was a profitable place to earn a living. The brothers collaborated with a range of writers, artists, and feminists, such as Annie Sprinkle, a certified sexologist, performance artist, former sex worker, author, and activist; Sharon McNight, one of most prominent female directors of pornography during the Golden Age; Margo St. James, famous sex workers’ rights advocate who commissioned a safe sex film from the Brothers and later brought a lawsuit against them for their exploitative stage fees; Deborah Sumdahl (Debi), a writer who worked at the O’Farrell as “Fanny Fatale” and co-founded the lesbian erotic magazine On Our Backs, with Nam Kinney and Myrna Elana, and worked on it with Susie Bright; Danielle Willis, writer and playwright; Joanne Scott, a former University of California scholar before dancing at the O’Farrell; and Bana Witt, poet with famed stage presence who read at Art Mitchell’s memorial. The Mitchell Brothers were also responsible for other ventures. Jim Mitchell, infuriated by the outbreak of the first Gulf War, launched the protest periodical War News; journalist Warren Hinckle was hired as editor, Robert Crumb designed the logo, and Art Spiegelman and Winston Smith were paid contributors. A proof sheet and issue of War News are included in the archive. Their professional partnership ended in 1991 when Jim Mitchell shot and killed Art Mitchell. Jim Mitchell was later convicted and served a prison sentence. The events surrounding the brothers’ careers and the circumstances of Art Mitchell’s death have been the subject of books and dramatized film portrayals.
