In practically every Marilyn Chambers Film, you will see a box of Ivory Snow Laundry Detergent Appear. Marilyn was actually chosen as the "Ivory Snow Girl" and appeared on the box and in promotions.... because of her "wholesome pure look". After she auditioned, but before she was selected, she filmed a porno named "behind the green door". Ivory subsequently put her face on their package, and promotions, not knowing about the film. This was pretty embarassing to them. They later added languages in their modelling contracts to prevent this.

In tribute, Marily puts a box of Ivory Snow in each of her films. Sometimes you will see her open a cabinet and look at it, then get a puzzled look on her face and close the door.
