The Pacific Theater was a San Francisco movie house owned by Graumann's Ltd. that operated from circa 1935 until it was closed in 1977. Its claim to fame was that it was permanently situated on the boardwalk, making it one of the few movie theaters in the world not located on land.
A common witticism in 1940s San Francisco, when all eyes were turned to a possible Japanese invasion of the American mainland, was the claim that the Army was fighting the Japanese "in the Pacific Theater" — which was true, as far as it went, since Pacific war movies were a staple of the Pacific Theater at that time. (The term "Pacific Theater" was also used for the war's western front with Japan.)
