“LOST” star Tania Raymonde (pictured above) and “True Blood’s” Brit Morgan will make their nude debuts in director Susanna Lo’s Manson Girls, a bio-pic that follows the violent and psychosexual lives of eight female Charles Manson cult members. The sexy duo partake in an orgy and share a girl-on-girl sex scene.

Raymonde and Morgan play convicted murderers Leslie Van Houten and Patricia Krenwinkel, respectively. In an interview with Lo for the website StayThirsty, the starlets reveal the lies they told themselves to justify going butt-nekid for the roles.

Raymonde says:

You can’t make a movie about the Manson girls without showing how the girls related to one another. They shared sexual connections as well as emotional ones. They were coerced and brainwashed into group sex situations that they more or less enjoyed.

Sex was the glue that held their family together. It’s important to show how these girls lived. I’m only portraying a character as accurately as I can, as I would with any role. As far as the nudity is concerned, I’ll get over it.

Morgan echoes Raymonde’s sentiment:

I have been avoiding nudity, for almost everything, so far in my career as well. So the sex scenes are new territory for me, but I am not as concerned as I imagined I’d be.

Probably because this is one of the only films I’ve read where it seems like it’s necessary and integral to the authenticity of the story. Sexuality was such an important factor in the 1960’s and in the lives of these girls, so I am willing to express that part of myself.
