You probably know the image even if you don’t know the name. A blonde, glowing young mother smiles down at a baby. She looks like the personification of 1970s wholesome America. This was the face of Ivory Snow laundry detergent, a product sold on being "99 and 44/100% pure."
Then she made a movie. Not just any movie, but a hardcore film called Behind the Green Door.
The fallout was nuclear. Procter & Gamble scrambled to pull boxes from shelves while the public realized their "pure" icon was now the biggest adult star in the world. Marilyn Chambers didn't just stumble into fame; she blew the doors off the American psyche.
The Girl from Westport
Marilyn Ann Briggs wasn't some runaway looking for a quick buck. She grew up in Westport, Connecticut, an affluent suburb. Her dad was an ad executive. Her mom was a nurse. Honestly, she was a bit of a local legend long before the cameras started rolling—a Junior Olympic diver and gymnast who graduated from Staples High School in 1970.
She wanted to be an actress. Period.
But the path to Hollywood is usually paved with bit parts and modeling gigs. While living in New York, she landed that famous Ivory Snow job. It paid well, and it put her face in every grocery store in the country. She even had a tiny, blink-and-you’ll-miss-it role in the Barbra Streisand flick The Owl and the Pussycat.
Eventually, she ended up in San Francisco. She was dancing topless to make ends meet when she saw an ad in the paper. The Mitchell brothers were looking for a lead for a "major" film.
Behind the Green Door: The Gamble
When she showed up for the audition, Marilyn didn't actually know it was a pornographic film. At least, not at first. Once the reality set in, she didn't run away. She was intrigued by the fantasy. She also had a sharp business mind—she demanded a percentage of the gross, which was unheard of for a newcomer.
Behind the Green Door (1972) changed everything.
It wasn't just a "dirty movie." It was high-budget for the time ($60,000) and surprisingly artistic. It was one of the first hardcore films to get a wide theatrical release in the U.S. It eventually grossed over $50 million.
The controversy was the best marketing she could have asked for. The "Ivory Snow Girl" was now a "porn actress," and the juxtaposition drove people crazy. People who had never stepped foot in an adult theater were suddenly curious. She became the first real "crossover" star.
The Mainstream Pivot and David Cronenberg
Marilyn didn't want to stay in adult films forever. In 1977, she did something truly bizarre for the time: she starred in a "legitimate" horror movie. David Cronenberg cast her as the lead in Rabid.

She plays a woman who develops a blood-sucking stinger in her armpit after a motorcycle accident. It’s weird. It’s dark. And she was actually good in it.
Cronenberg later claimed he’d never even seen her adult work; he just liked her look—that "girl next door with a secret" vibe. For a moment, it looked like she might actually make it in Hollywood. She did dinner theater, released music, and even appeared on The Merv Griffin Show.
But the stigma was heavy.
Society in the late 70s and 80s wasn't ready to let a woman be both a serious actress and a former porn star. She eventually went back to the adult industry with the 1980 film Insatiable, which was another massive hit. She spent the rest of her career bouncing between the two worlds, always trying to prove she was more than just a label.
Politics and the Later Years

Twice.
In 2004 and 2008, she was the running mate for Charles Jay on the Personal Choice Party ticket (and later the Boston Tea Party). She didn't win, obviously, but she took it seriously. She was a libertarian at heart, believing in body autonomy and limited government.
By the time she reached her 50s, the "glamour" had faded a bit. She lived in a trailer park in California, working a regular job at a car dealership and doing the occasional appearance at Comic-Con. Her friends described her as a "classy lady" who loved gardening and was fiercely proud of her daughter, McKenna.
Why She Matters Now
Marilyn Chambers wasn't just a porn actress; she was a cultural lightning rod. She forced America to look at the hypocrisy of its "purity" standards. You can't put a woman on a pedestal as a "pure" mother figure and then crucify her for owning her sexuality.
She proved that you could be a talented athlete, a mother, a political candidate, and a sex worker all at once.
She died in 2009 of a brain aneurysm at age 56. There were no drugs in her system. She was just a woman who lived a loud, complicated life on her own terms.

If you're researching the history of the sexual revolution or the evolution of celebrity culture, you have to start with the 1970s "Golden Age." Specifically, look into the Mitchell Brothers' impact on San Francisco's film scene and how Behind the Green Door was used as a test case for First Amendment rights in the Supreme Court case Ballew v. Georgia.
