Camera and makeup illusions help to make Eric LLoyd who's actually 11 years old play a 7 year old. And Sook who's supposed to be the oldest sister, but believed to be not very bright is governed by Jennie who has assumed head of household. The other two cousins are supposed to the youngest. When this was filmed Piper Laurie (Jennie) is 65, Jeffrey DeMunn (Seabone) is 50, Anita Gillette (Callie) is 61, and Patty Duke (Sook) who was supposed to be the oldest cousin was 51.
