History in the Movies
My searching turned me onto the History in the Movies website. It's run by an Illinois history professor, and answers various questions about the historical details of period films.
One answer that makes me feel better is from the movie Ray. In the film, it's said that Georgia banned Ray Charles from playing in the state from 1962 until 1979, at which time the legislature apologized. There are even images of newspaper headlines about the ban. But when the Augusta Chronicle did some research, it turned out that no such ban ever existed. Even the headlines were fabricated. As a Georgian, I'm glad that bit of our state history turned out to be fictional.
