Trivia

Actress Sharon Tate's sister Debra Tate, has stated she does not support the Hilary Duff movie about her sister's life, Debra said, "It's been exploitative since day one. It's been the case since the media went crazy and has perpetuated mistruths making things even more salacious. It's now morphed into something that is more fictionalized than truth at this point. To celebrate the killers and the darkest portion of society as being sexy or acceptable in any way, shape or form is just perpetuating the worst of our society. I am vehemently opposed to anything that does that. I've been dealing with this for 50 years now. We need to stop this, and I intend to help the family behind the NoNotoriety anyway I can to help make this a national movement."
