The "40 Acres" back lot was the location where the exterior shots of The Andy Griffith Show were filmed. It was actually about 29 acres of land in Culver City, California. It worked as a backdrop for numerous silent films as well as Gone With the Wind. By 1976 the back lot was in disrepair and bulldozed.
Interior shots of The Andy Griffith Show were filmed at the Desilu Studios in Cahuenga at stages 1 & 2.
