Irene Ryan played Granny on The Beverly Hillbillies. The matriarch of the Beverly Hillbillies (1962-1971), played by Irene Ryan. The character's name was "Daisy Moses," but I don't think she was ever called anything except "Granny" in the show.
The name of the company that bought the Beverly Hillbillies'' land was O.K. Oil Company. Jed Clampett sold it to them, received a fortune, and used that fortune to move his family to Beverly Hills in California.
According to the official documentary, Legend of the Beverly Hillbillies, Jed the character moved back to the Hills after Mr. Drysdale stole all of his money! Imagine that. The actor who played Jed, Buddy Ebsen, went on to play a detective named Barnaby Jones in a show by the same name.
Jed's daughter Elly May Clampett (Donna Douglas) is Jethro's cousin. Technically he and his "Uncle Jed" are also cousins, because he is the son of Jed's cousin Pearl. Jethrine Bodine (also played by Max Baer, Jr.) was Jethro's twin sister.
It doesn"t take place in or around a theatre. there was a theatre with a very small marquee in the rural town of Hooterville, the locus of Petticoat Junction and Green Acres- Green Acres was the farm, Hooterville the town. so it goes.
