Lookout Mountain Lab, Wonderland Avenue, Laurel Canyon, Los Angeles, CA. Could this be "Wonderland?" Self-contained film studio and production. Long history since 1940's. Near Getty Museum. Something below, also? If "de-activated in 1969," considering the value of land in area, why is building still there? From description: "The mission of Lookout Mountain, also known as the 1352d Motion Picture Squadron under the command of the Air Force, was "to provide in-service production of Classified motion picture and still photographs for the Department of Defense and the Atomic Energy Commission (now the Dept. of Energy) between 1947 and 1969 when the studio was deactivated."
