I've got a 30th anniversary DVD of "Blazing Saddles" There's an interview with Mel Brooks included. He talks about how it would be impossible to make that movie today.
Pretty funny considering how bad some of the crap is they churn out now. You can show a person being flayed alive, or literally torn apart,.. but try standing on a rooftop and yelling, "The Sheriff's a nigBOOONNNNG."
