According to director Herschell Gordon Lewis, the founder of Kentucky Fried Chicken, Colonel Harland Sanders, whose company supplied Lewis' production company and advertising firm with fried chicken during the filming of this and other movies, insisted on appearing in a cameo at a KFC restaurant located in Wilmette, Illinois. Lewis recalled that Colonel Sanders was very difficult to work with because Sanders made several unreasonable and self-serving demands for, among many things, multiple rehearsals, top-billing, and wanting to direct the scene himself.
When the kids play outside a Col. Sanders Kentucky Fried Chicken restaurant, the old gentleman with the bucket of chicken who comes out and dances with them really is Col. Harland Sanders.
