Kim Dawson (credited as Kim Sill) said it was really tough pretending to have sex with an invisible man. She said when she performs sex scenes with other actors, she can work off them and their moves. But she was totally naked and by herself. They had to keep restarting the scene because she kept laughing at how silly she felt. The director finally started giving her direction on how to move and that helped.
Daneen Boone said she loved doing this role because her character Samantha is very wild. It's the total opposite of the sweet and innocent character she just finished playing in the seven Justine movies. She also thought that it was funny that she went to Catholic school as a girl and hated wearing the uniform, then she got cast in this and they made her wear a Catholic schoolgirl uniform.
Producers hired a female mime to show Doreen Boone and Kim Dawson how to make love to an invisible man. Boone had to do her scene in a shower. She said she had the moves down so well that it only took 20 minutes to film.
