RKO Forty Acres was a film studio backlot owned by RKO Pictures and later Desilu Productions, located in Culver City, California. Best known as Forty Acres, or "the back forty", it had other names such as "Desilu Culver", the "RKO backlot" and "Pathé 40 Acre Ranch" depending on which studio owned the property at the time. For nearly fifty years it was known for its outdoor full-scale sets such as Western Street and Atlanta Street or Main Street and was used in films like King Kong (1933) and Gone with the Wind (1939), and television shows like Bonanza and Star Trek. It was situated on a triangular parcel of land that measured 28 ¹⁄₂ acres (11.5 ha), located a few blocks from RKO (now "The Culver Studios") which was situated to the west. It was bounded by Higuera Street to the north, West Jefferson Boulevard, Ballona Creek and Culver City Park to the south and Lucerne Avenue to the west. In 1976 it was razed for re-development and is known today as the southern expansion of the Hayden Industrial Tract. A number of the buildings in the industrial park have been converted to television studios.
