The Warner Grand Theatre is a historic movie palace that opened on January 20, 1931. It is located in San Pedro, Los Angeles, California, at 478 West 6th Street. The design of the Warner Grand Theatre was a collaboration by architect B. Marcus Priteca and interior designer Anthony Heinsbergen, in the Art Deco—Moderne style. It was one of three similarly lavish Los Angeles area Art Deco movie palaces on which Priteca and Heinsbergen collaborated for the Warner Bros. company in the early 1930s. The others were located in Beverly Hills and Huntington Park. Priteca later designed Hollywood's famous Pantages Theatre.
