Quentin Tarantino has won over Sharon Tate's sister after agreeing to meet with her to discuss his plans for new movie 'Once Upon a Time in Hollywood'. Debra Tate was quick to hammer the director's plans to include her late sister's 1969 death at the hands of the Manson Family cult members in his new film, which stars Leonardo DiCaprio and Brad Pitt, and she made it clear she wasn't thrilled by news of his decision to cast Australian Margot Robbie as the pregnant Sharon.
