Rated 100% at Rotten Tomatoes! Sample review:
In 1976, feminist sex researcher Shere Hite published The Hite Report. Based on anonymous survey responses about sex from thousands of women across the US, this groundbreaking book would become a catalyst for putting discussions of female sexuality in the spotlight. Despite selling millions of copies (with the documentary claiming it to be the 30th bestselling book of all time), little is spoken about the book’s author today. Filmmaker Nicole Newnham strives to put Hite’s name back in the public sphere with documentary The Disappearance of Shere Hite by giving an account of her fascinating life alongside the media backlash that would bury her name and reputation.
The nudity comes from a look back at Hite’s careers in modeling and acting.

Another image of her, and which I particularly like:
Yea, she came and went in a hurry ~ that’s all i got.
