One reason The Founder got a lot of press - there was a book about Joan Kroc published
about the same time the movie was released. I've not read the book but did speak with the author many times. She did five years of research, talked to a lot of people, and learned
far more about McDonald's than was her original goal.
For those who have seen the movie the "fact check" section of her blog will be interesting,
maybe even for those who've not seen the movie.
