What Were the Most Shocked at About Rosa Parks?

I was shocked when I was told that there had never been a full length doc in Rosa Parks. We opened the doc with a great show called To Tell the Truth, which people of a certain age will do. And all the celebrities get it wrong until they come to Nipsey Russell who has to recuse himself because he says he knows Rosa Parks. It sounds like you learned a lot from making this movie or from putting this together. What were the things that really were shocked by?
