I got this book (version I have was written in 1973-it appears it's been updated) from a freecycling library system they have set up in DC. I'm on the Twenties chapter.
The writer says she's a feminist. Also a film critic, which she states is her primary role. Keep in mind that a feminist 46 years ago is cat years away from what they are today. She is actually quite critical about some feminists who hate men.
It's an interesting read so far and I actually want to brush up on old movies from what I have read so far.
