In a 2015 interview with The Wrap, director Nick Cassavetes supported the idea of people having incestuous relationships and compared it to being gay. He said, "I have no experience with incest. We had heard a few stories where brothers and sisters were completely, absolutely in love with one another. You know what? This whole movie is about judgment, and lack of it, and doing what you want. Who gives a shit if people judge you? I'm not saying this is an absolute, but in a way, if you're not having kids, who gives a damn? Love who you want. Isn't that what we say? Gay marriage -- love who you want? If it's your brother or sister it's super-weird, but if you look at it, you're not hurting anybody except every single person who freaks out because you're in love with one another." He said he decided to add the element of incest to the story because he felt something had to happen to the main character that was "traumatic and beautiful and made her a pariah." He added, "She's a wipeout of a mess. But I hope people root for this character, damaged or not."
