Writer/director Nick Cassavetes supports the phrase "If you can't keep it in your pants, keep it in the family" ... claiming there's nothing wrong with a little incest.
Cassavetes, whose new film "Yellow" features a brother/sister relationship, compared the taboo act to gay marriage while promoting the movie in Toronto this weekend.
Cassavetes explained, "Who gives a s**t 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?"
He continued, "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.”
