Long before the Kardashians had multiple TV shows on E!, Ozzy Osbourne had ever unintelligibly bellowed out “Sharon,” or Jon and Kate’s eight were even a twinkle in their eye, there was a family called the Louds who were the subject of a 1973 PBS documentary series called An American Family. Considered one of the first reality TV series, it also tackled many taboos of the day, chronicling Bill and Pat Loud’s separation and eventual divorce, as well as the sexuality of their openly gay son, Lance. HBO’s upcoming original movie Cinema Verite, which stars Diane Lane, Tim Robbins, and James Gandolfini, provides an imagined look at what went on behind-the-scenes as cameras took over their Santa Barbara home.
