A taboo chapter in Black history

The year was 1972, and interracial dating had yet to be widely accepted despite the few dots of black-and-white couples that dotted the landscape around the United States. But for the Mitchell brothers, not only would their new porn film usher in the hardcore age, it would literally smash the remaining barriers between the races.
In the film, Marilyn Chambers, a squeaky clean actress whose claim to fame was an Ivory Snow advertisement, had sex with a well-endowed African-American actor by the name of Johnny Keyes. The scene was so electric that the movie "Behind the Green Door" took the country by storm. Chambers, for her part, fainted at the end of one scene lasting over 45 minutes. The porno industry and American audience was shocked by the still-taboo spectacle of a white woman having sex with a black man.
Although they've made up now, it was reported that Chambers' own parents refused to speak to her for several years after the film's release.
The movie and the sex scene was a dubious first for Chambers, Keyes and the country. And Chambers became a big porn star. "Crucial" Keyes' career in adult movies took off as well, but he eventually faded into the background. Chambers? She wondered in and out of porn for the next 30 years, making a film as recently as 2005 at age 54. But she's turned political as well. She ran for president in 2004 on the Personal Choice Party ticket.
