Esther's last name Woodhouse is a tribute to Rosemary's Baby (1968) character Rosemary Woodhouse.
Kristina Klebe's last nude scene. She first appeared fully nude in Halloween (2007), even though she didn't want to, because it was her first major role and she'd do anything to get it. The nudity wasn't the issue, though, it was seeing images of her body posted all over the Internet, which she hated. She refused to take any more nude roles after that until this film, because, unlike the gratuitous nudity in Halloween, she felt it fit her character in the scene. But she refused to remove her panties even though it didn't make sense since she was masterbating. After this role, she turned down any project that required her to be naked.
