Speaking of Dick Van Dyke, he wrote a book (maybe 10 years ago?) about his life. He talked about how Walt Disney wanted him in his Disney movies. Walt explained the main reason why was because of an interview Van Dyke gave espousing family values. Walt felt that made him a great role model for the Disney fans. Times have certainly changed in that regard, and not for the better.
He might still be a great role model for the fans, but certainly not for Disney employees and management, who want Disney to mass market kiddie porn.
