- Due to the tight fitting gossamer gown, Kym Herrin was fitted for a mold. The crew had to put Vaseline all over her body but were being "delicate." Sensing that approach would take too long, Herrin grabbed one of the crewmen and placed his hand on one of her breasts and said, 'Let's get on with this!'

We made this tight fitting gossamer gown she was wearing, sort of flowing, and she was shot against black. To make a mold, everybody sort of rubbed Vaseline delicately around in places and she finally grabbed one of the guys and said 'Let's get on with this!' and grabbed his hand [motions hand on chest]."
