Goldie plays Sharon Tate???
Since Beatty's George is based on Jay Sebring, Goldie's Jill must be Sharon Tate. In the first scene alone their are at least 4 suggestions that indeed she is. She hears gun Shots in the canyon, she tells of a reacurring dream that she has of being held captive, talks about having a baby but has fears about the world which ironically fall in line with Manson politics and the TV is showing some drama of a women being roughly treated. Goldie even looks like Tate.
If you know about the Tate-Sebring relationship circa 64'? to 69' you will find many parallels, which have been cloaked and watered down. See if you can guess who is playing Polanski.
I only mention this because I've never heard it suggested before. It's almost tastlessly blatant, but it isn't.
Great film!
