Originally, it was Paul Henning’s intention to cast Bea Benaderet in the role of “Granny.” He had known Benaderet for a number of years, and admired her work. However, Irene Ryan really nailed the audition, and it was Benaderet herself who told Henning that Ryan should get the part. Out of loyalty to Bea Benaderet, Paul Henning then added the character of “Cousin Pearl” for her, and later cast her in the lead of “Petticoat Junction.”
Didn’t know that! Cool!
