RKO Forty Acres was a film studio backlot in the United States, owned by RKO Pictures (and later Desilu Productions), located in Culver City, California. Best known as Forty Acres and "the back forty," it was also called "Desilu Culver," the "RKO backlot," and "Pathé 40 Acre Ranch," depending on which studio owned the property at the time. For nearly 50 years it was known for its outdoor full-scale sets, such as Western Street, Atlanta Street, and Main Street and was used in many films (including King Kong (1933) and Gone with the Wind (1939)) and television series (such as Bonanza and Star Trek).
