Mann sold the theaters to General Cinema Corporation in 1970 and moved to California. The first production to his credit was 1969's The Illustrated Man, based on a Ray Bradburybook. He didn't stay out of the theater business for long, and purchased the troubled 276-screen National General Theatre chain in 1973. Mann soon expanded the chain to 360 screens, but again sold off his theaters in 1986, this time to Gulf+Western, which later renamed itself to Paramount Communications (which itself became part of Viacom). Grauman's Theater eventually regained its original name in late 2001.
