HBO's "Cinema Verite" offers glimpses of the making of the first "reality" show, "An American Family" from 1973. The Loud family of Santa Barbara was profiled and over the course of the series, the peeling away of their seemingly perfect (boring!) family facade reveals a much more interesting cast of characters.
Perhaps the most interesting was the eldest son, Lance, who moved to New York and took up with the Warhol gang, eventually becoming a writer for "Interview" and lead singer of the Mumps. Lance died of AIDS, at 50.
